CVS commit: src/sys/ddb

Module Name:    src
Committed By:   christos
Date:           Sat Dec  3 16:25:50 UTC 2011

Modified Files:
        src/sys/ddb: db_xxx.c

Log Message:
If we are DIAGNOSTIC don't try to go further if we failed to take the
lock, because we are going to trigger a KASSERT. Also hold the lock
longer and take the proc lock for kpsignal(). Maybe we should add
mutex_steal() and mutex_return() for the debugger? Lock correction
suggestion from jmcneill.
