legacy code), if the builtin service forks (not all do), avoid leaking
listening sockets into the child process.
If the child process were to keep copies of the listening sockets
around and then hang about for a long time, it would prevent inetd
from being able to re-bind them upon restart.
The listening sockets are tagged close-on-exec, but that doesn't help
when one doesn't exec.
Patch from my own very old PR 8253.

the desired behavior without having to change libwrap.

Also extending the UDF implementation to support symbolic links and

Limitations:
all operations can be performed on the file system though the
sheduling is currently optimised for archiving workloads.
mv(1)/rename(2) is currently only implemented for non-directories.
Port identifycpu() to userspace. The kernel lies and reports on cpuN while
actually using the values from cpu0, but this attempts to bind itself to the
requested CPU if running as root. That doesn't work properly yet due to
kern/38588, but will do once that's fixed.
one of the following:
- Holding kernel_lock (indicating that the code is not MT safe).
- Bracketing critical sections with kpreempt_disable/kpreempt_enable.
- Holding the interrupt priority level above IPL_NONE.
Statistics on kernel preemption are reported via event counters, and
where preemption is deferred for some reason, it's also reported via
lockstat. The LWP priority at which preemption is triggered is tuneable
via sysctl.

* Add a new flag: -T. When it's enabled statistics will be created for
the sensors. Max, min and average statistics as well as sensor unit
will be displayed. Must be used with an interval.

Changes beyond OpenBSD's driver:
- Improved support for AMD K8
- Added support for AMD Barcelona, AMD Phenom and AMD Griffin
Tested on various single and multi-socket machines.

You can do something like the following now:
$ envstat -s "acpibat0:charge,acpibat0:charge state,acpitz0:temperature"
[acpibat0]
charge: 3.015 Ah (79.70%)
charge state: NORMAL
[acpitz0]
temperature: 54.000 degC

* As bonus, the code has been modified to use a simple queue for
the sensors, and this has simplified and improved some parts of the
code as well.

btuartd(8) should be named btattach(8) for consistency
with other parts of NetBSD
make btattach(8) a single-use tool for less complexity
device specicific initialisation (from btuart(4)) is carried
out prior to activating the line discipline (in btattach(8)),
which simplifies the API somewhat and means that the user
tool and the kernel do not need to be kept in sync.
btuart(4) driver is much reduced; naming is made consistent
and all tsleep() and delay() are removed to userland
there are no waiters. This gives a major boost to build.sh on larger
systems as directory vnode locks are exclusive for lookup, but are often
only held for a very short period of time.
This change has the potential to more readily expose lock order reversals
and other types of deadlock.

Provide a separate ypdb_mktemp() API to open a temporary file read-write.
Use mkstemp() instead of mktemp().
NOTE: makedbm & mkalias tested ok. I couldn't test ypxfer.

filed.
- Kill checkalias(). Allow multiple vnodes to reference a single device.
- Don't play dangerous tricks with block vnodes to ensure that only one
vnode can describe a block device. Instead, prohibit concurrent opens of
block devices. As a bonus remove the unreliable code that prevents
multiple file system mounts on the same device. It's no longer needed.
- Track opens by vnode and by device. Issue cdev_close() when the last open
goes away, instead of abusing vnode::v_usecount to tell if the device is
open.
