Summary: tempfile.mktemp() omits pid from name

Initial Comment:
In python2.2 names created using tempfile.mktemp() 
contained the current pid as a prefix.
This behaviour has changed and now processes running 
concurrently are prone to races.
1.) In my application which forks a few thousand sub 
processes over time sometimes tempfiles created by one 
subprocess are deleted by another.
2.) Also this probably leads to longer creation times 
when two processes want to create a temp file at the 
same time on multiprocessor machines because both 
processes are using the same rng with the same seed to 
generate names.
Sorry, no code here, because 1. happens only a few 
times when running with huge amounts of data and 
because 2. is only a speculation.

I would propose to reinstate the former behaviour.
