- if the process does not exist anymore, return NULL
- if the process has created more lwps retry
XXX[1]: We should fix sysctl_kern_lwp() to return the number of lwps it
needs in oldlenp when ENOMEM. The we can avoid calling sysctl
twice (by starting let's say with always 1 lwp, or 10).
XXX[2]: We should fix kvm_getlwps to never spit errors.

filesystem on a vnd partition for me. It did grow the filesystem, and after
a fsck -f on the partition to fix a few superblock inconsistencies, all
looks good.
Fix a bug in sblock() that has existed since revision 1.1 from BSD:
correctly return an error if M_NOWAIT is passed to sblock() and the
operation might block. This remarkably subtle macro bug appears to
be responsible for quite a few undiagnosed socket buffer corruption
and mbuf-related kernel panics.
o If a long option looks like an ambiguous abbreviation of two or more long
options, but all the possible interpretations would return the same
value, then just return that value without complaining that it's
ambiguous.
o If a long option could be interpreted either as an exact match for one
long option, or as an abbreviation for one or more other long options,
then treat it as the exact match.
These changes align NetBSD's getopt_long(3) with the current behavior of
GNU getopt_long(3), the de facto standard, and FreeBSD's getopt_long(3).
- Add support for the IT8716F chip, patch from FUKUMOTO Atsushi via
PR port-i386/35796.
- Enable the flag ENVSYS_FCHANGERFACT in voltage sensors, to be able to
increment the value returned by the driver via envstat(8).
- Update VBAT sensor reading every time we read it, otherwise it will
always report the power on value.
- Enable all sensors that were missing before: 3 Temp + 3 Fan + 9 Voltage.
- Add new registers to set high/low limits in temperature/voltage sensors
(still unused).
- Disable some sensors if they are reporting bogus data or simply they are
not connected.

with an asterisk, as was suggested by Greg. A. Woods.
Example:
$ ./envstat -dlm0 -s "CPU Fan,System Fan,Aux Fan"
System Fan: *
CPU Fan: 1308 RPM
Aux Fan: *
$
Except Integer and Driver sensors, which shouldn't need that.
1) Comply with the way buffercache(9) is intended to be used. Now we
read in single blocks of EFS_BB_SIZE, never taking in variable
length extents with a single bread() call.
2) Handle symlinks with more than one extent. There's no reason for
this to ever happen, but it's handled now.
3) Finally, add a hint to our iteration initialiser so we can start
from the desired offset, rather than naively looping through from
the beginning each time. Since we can binary search the correct
location quickly, this improves large sequential reads by about
40% with 128MB files. Improvement should increase with file size.
When reading a file, we would erroneously iterate to the next extent
before having filled the entire uio request. This lead to unnecessary
extent iteration and excessive calls to efs_read.
Sequential read performance has doubled in the uncached case and
quadrupled when data is buffered.
