CVS commit: src/sys/kern

Module Name:    src
Committed By:   christos
Date:           Fri Sep  2 20:06:29 UTC 2011

Modified Files:
        src/sys/kern: kern_fork.c

Log Message:
Add support for PTRACE_FORK. NB: This does not (yet) work for vfork(), because:
1. When we vfork() PL_PPWAIT is set, and that makes us do regular disposition
   of the TRAP signal, and not indirect through the debugger.
2. The parent needs to keep running, so that the debugger can release it.
   Unfortunately, with vfork() we cannot release the parent because it will
   eventually core-dump since the parent and the child cannot run on the
   same address space.
