CVS commit: [nathanw_sa] syssrc/sys/kern

[Nathan J Williams <nathanw%netbsd.org@localhost>]

Module Name:    syssrc
Committed By:   nathanw
Date:           Wed Oct  9 16:57:28 UTC 2002

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.
