RELENG_4_5 doex not have this patch. It probably should. I am CCing
the security-officer.
relevant information for security-officer: This is 1.213 (current)
and 1.187.2.13 (stable) of vm/vm_map.c). It's a very simple and
obvious patch.

:> Yes, this has been fixed. Python was using MAP_ANON|MAP_NOSYNC
:> mmap()'s and this resulted in the possibility of msync() encountering
:> an optimized vm_map_entry that did not yet have a VM object associated
:> with it, causing a panic.
:>
:> Both -stable and -current have been fixed to handle the case.
:> -current was fixed on March 7th, and -stable on March 8th.

:Does that mean that RELENG_4_5 has that patched also?
