* Do not use explicit paragraphing (Pp) to separate list items.
* Do not use semi-colons to punctuate list items; the use or
periods eases maintenance.
* Do not mark up external shell commands as internal commands
(Ic).
* Do not introduce new hard sentence breaks.
the PnP probe is merely a stub as we make assumptions about some of this
hardware before we have probed it.
Since these devices (with the exception of the speaker) are 'standard',
suppress output in the !bootverbose case to clean up the probe messages
somewhat.
The only change in the default functionality should be that
the output reports are slightly more verbose WRT files deleted.

1) while allocating a uidinfo struct malloc is called with M_WAITOK,
it's possible that while asleep another process by the same user
could have woken up earlier and inserted an entry into the uid
hash table. Having redundant entries causes inconsistancies that
we can't handle.
fix: do a non-waiting malloc, and if that fails then do a blocking
malloc, after waking up check that no one else has inserted an entry
for us already.
2) Because many checks for sbsize were done as "test then set" in a non
atomic manner it was possible to exceed the limits put up via races.
fix: instead of querying the count then setting, we just attempt to
set the count and leave it up to the function to return success or
failure.
3) The uidinfo code was inlining and repeating, lookups and insertions
and deletions needed to be in their own functions for clarity.

filesystem not being kq-aware), then fall back to using sleep. This
allows tail to work with NFS filesystems again without chewing up CPU time.
When given the -F flag, resort to sleep/stat after the file was moved
or deleted. This allows a window where the file being tailed does not
exist at all, which is typically the case during log rotation. Switch
back to using kq (if possible) after the file is reopened.
When re-adding an event, do not reset the event state. If the event was
pending, it will remain pending. This allows the user to change the udata
field after the event was registered, while not losing any events which
have already occurred.

options. This allows you to set the standard dynamic port
assignment range prior to any network daemons (like named) starting
up, necessary if you are also using a firewall to restrict lower ports.
