e4c2ac1637 Sorry folks; I accidentally committed a patch from what I was working 
on a couple of days ago.  This should be the most recent changes.

7cd650a972 - Set the ke_cpu field in sched_add() for interrupt and realtime threads 
since they are going on the current cpu and not their previously assigned
   cpu.
 - sched_runnable() should only return true in the SMP case if the other
   processor has more than one thread that is runnable.  We can not steal
   curthread.
 - Change kseq_print() to accept the cpuid instead of a kseq pointer.  This
   makes use of this function in ddb much easier.

a0240e2cb0 Revamp libpthread so that it has a chance of working in an SMP 
environment.  This includes support for multiple KSEs and KSEGs.

The ability to create more than 1 KSE via pthread_setconcurrency()
is in the works as well as support for PTHREAD_SCOPE_SYSTEM threads.
Those should come shortly.

There are still some known issues which davidxu and I are working
on, but it'll make it easier for us by committing what we have.

This library now passes all of the ACE tests that libc_r passes
with the exception of one.  It also seems to work OK with KDE
including konqueror, kwrite, etc.  I haven't been able to get
mozilla to run due to lack of java plugin, so I'd be interested
to see how it works with that.

69297bf8c9 suser() does not need the proc lock, just the setting of P_PROTECTED in

b68e08498f The sched_lock is not needed while clearing two of the P_STOPPED bits in 
p_flag.  Also, the proc lock can't be recursed, so simplify an older proc
lock assertion.

b5a2bad175 Don't assume that p_session hasn't changed out from under us after unlocking 
the process and session.  Instead, cache a true reference to the session
when we do the hold and release our reference on that session.  This avoids
the need for the proc lock when dropping the reference.
