Modified Files:
	syssrc/sys/kern [nathanw_sa]: kern_sa.c

Log Message:
If sa_switch() fails, have the next LWP go into sa_yield() rather than
blithely calling mi_switch(), so that the invariants about running
vs. idle LWPs are maintained. Also, be sure not to set L_SA_UPCALL
when waking up if we didn't successfully make the BLOCKED upcall.

Add some stack count debugging.
