- use glob patterns when matching packages by origin
- csh-style {...} choices in glob matching
- pkg_info: new flag -E (list matching package names only)
- pkg_version: new flag -T (test if a given name matches a pattern)
- new flag -X (interpret pattern as an extended regular expression)

pv entries per 1GB of user virtual memory. (eg: if we had 1GB file was
mmaped into 30 processes, that would theoretically reduce the KVA demand by
30MB for pv entries. In reality though, we limit pv entries so we don't
have that many at once.)
We used to store the vm_page_t for the page table page. But we recently
had the pa of the ptp, or can calculate it fairly quickly. If we wanted
to avoid the shift/mask operation in pmap_pde(), we could recover the
pa but that means we have to store it for a while.
This does not measurably change performance.

creation of the sysctl tree for the turnstile profiling stats until a
SI_SUB_LOCK sysinit. Doing it in init_turnstiles() is too early as it is
called before mi_startup().
hash tables used in the sleep queue and turnstile code. Each option adds
a sysctl tree under debug containing the maximum depth of any bucket in
the hash table as well as a separate node for each bucket (or chain)
containing the current depth and maximum depth for that bucket.
vm objects shadowing source in vm_object_shadow(). This closes a race where
vm_object_collapse() could be called with a partially uninitialized object
argument causing symptoms that looked like hardware problems, e.g. signal 6,
10, 11 or a /bin/sh busy-waiting for a nonexistant child process.
the queue has been removed from the global taskqueue_queues list. This
removes the need for the draining queue hack.
- Allow taskqueue_run() to be called with the taskqueue mutex held. It
can still be called without the lock for API compatiblity. In that case
it will acquire the lock internally.
- Don't lock the individual queue mutex in taskqueue_find() until after the
strcmp as the global queues mutex is sufficient for the strcmp.
- Simplify taskqueue_thread_loop() now that it can hold the lock across
taskqueue_run().

and bump all of the taskqueue swi's to 6. This gives callouts higher
priority than taskqueue tasks and gives all taskqueue tasks the same
priority.

applied to their permissions. Just calculate the
default dir mode once and use it consistently, rather than
trying to remember to calculate it everywhere it's needed.
