[issue7193] Popen blocks program from another thread

[Dan Griffin]

New submission from Dan Griffin <dgriff1 at gmail.com>:

When I create a thread that does a Popen it blocks the entire program. I
have attached a simple sample program. Whether I do Popen.wait or
Popen.poll the program blocks. I have done this on OSX 10.5 and 10.6. I
have not yet tried ussing the multiprocessing module.
