looks like good news. Think you are right.
Checked a little bit with
on Linux 22.214.171.124-0.2-default #1 SMP 2008-12-18 10:17:03 +0100 i686 athlon i386 GNU/Linux
works fine AFAIS.
What puzzles me still is a pure python question -
do we need this `read()' here, i.e. if a file opened is
delivered to exec, will it not being read anyway?
