Log Message:

        sys/miscfs/procfs/procfs_vnops.c: revision 1.158
Don't allow getcwd() on procfs vnodes and provide "/" as the path
instead of the result from getcwd().  The works around locking
panics caused by namei calling VOP_READLINK while holding on to a
directory lock and getcwd() trying to acquire that lock.  The real
fix would be to get rid of getcwd() calls within VOPs (not locking
safe), but that's not a viable option in the netbsd-4 timeframe.
Suggestion for workaround from David Holland.
