Message 151762 - Python tracker

For FreeBSD, Python 3.2 and 3.3 now check to see if /dev/fd is valid.  Be sure and "mount -t fdescfs none /dev/fd" on FreeBSD if you want faster subprocess launching.  Run a FreeBSD buildbot?  Please do it!

For Python 3.1 the fix for #13788 would fix this, but I believe 3.1 is in security fix only mode at this point so we're not going to backport that os.closerange change that far.
