Correct a bug that should have wreaked havoc everywhere, but for
some reason only bit unlucky people who use `-march' optimizations.
The compiler cannot assist one in distinguishing between the two
function calls below.

   nsdispatch(&discard, ...);  /* correct .. no, really! */

b874183561 Change the locking so that the _modify function is called with topology 
held.

The only place where we want to not hold topology is when we read
(or write) the label to disk: in the case of a disk error with a
long recovery time, holding topology would prevent open/close of
any disk device.

9752f794c7 - Move PS_PROFIL and its new cousin PS_STOPPROF back over to p_flag and

0b5318c81a - Assert that the proc lock and sched_lock are held in sched_nice(). 
- For the 4BSD scheduler, this means that all callers of the static
  function resetpriority() now always hold sched_lock, so don't lock
  sched_lock explicitly in that function.

a15cc35909 Lock both the proc lock and sched_lock when calling sched_nice since 
kg_nice is now protected by both.  Being protected by both means that
other places in the kernel that want to read kg_nice only need one of the
two locks.

6dee371a55 Add a couple asserts to pthread_cond_foo to ensure the (low-level) 
lock level is 0.  Thus far, the threads implementation doesn't use
mutexes or condition variables so the lock level should be 0.

Save the return value when trying to schedule a new thread and
use this to return an error from pthread_create().

Change the max sleep time for an idle KSE to 1 minute from 2 minutes.

Maintain a count of the number of KSEs within a KSEG.

With these changes scope system threads seem to work, but heavy
use of them crash the kernel (supposedly VM bugs).
