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.

This diff is from Doug Needham who found an easy way to get
the desired behavior without having to change libwrap.
and DVD's behave like floppy discs. Writing is supported upto and including
version 2.01; version 2.50 and 2.60 will follow.
Also extending the UDF implementation to support symbolic links and
hardlinks.
Added are the mmcformat(8) tool to format rewritable CD/DVD discs and
newfs_udf(8).
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.
