Doing a google search on

    tempfile security

turns up hundreds of rants.  Have fun <wink>.  There does appear to be a
real vulnerability here somewhere (not necessarily Python), but the closest
I found to a clear explanation in 10 minutes was an annoyed paragraph,
saying that if I didn't already understand the problem I should turn in my
Unix Security Expert badge immediately.  Unfortunately, Bill Gates never
issued one of those to me.

Certainly not the patch he posted!  And for reasons I sketched in my
patches-list commentary, I doubt any hack based on pseudo-random numbers
*can* solve anything.
