        src/sys/rump/librump/rumpkern: locks.c

Log Message:
If we are "unsleepable" due to a dying proc, yield() instead of
returning directly.  This allows other threads to run possible
setting a condition we are waiting on.

Fixes a busyloop condition which could be entered from vfs_unmountall()
where we were waiting for vrele_pending and the vrele thread could
not run since we were hogging the CPU.
