Summary: subprocess.Popen inside thread locks the thread in some case
Initial Comment:
The bug can be verified with the example program
attached to this bugs. Two files are attached:
my_thread.py and main.py
When main.py is executed the thread hangs on
subprocess.Popen, while my_thread.py, which is imported
by main.py runs without problems. In fact both should
do exactly the same since main.py doesn nothing but
importing my_thread.
My python version:
Python 2.4.2 (#1, Oct 17 2005, 09:05:20)
[GCC 3.3.6 (Gentoo 3.3.6, ssp-3.3.6-1.0, pie-8.7.8)] on
linux2
If any more info is required,

I cannot reproduce this error on ubuntu linux using python
2.4.2.
However, I am able to reproduce it using python 2.4.2
running on FreeBSD 4.11.
Stopping the program with ctrl-c results in the following
output:
