Installer 5b3 problem

[Zoltan Felleg]

Hello,

If this list is not the right place for this stuff, please redirect me 
to the proper one (and forgive me for bothering you here).
I have a problem with the new mcmillan installer, namely the following 
code freezes at the commands.getstatusoutput() line when its function 
runs as a thread. The script itself works correctly, the "frozen" 
executable does not. (It did work with installer 5b2). The system is Red 
Hat Linux 7.2, with Python 2.2 compiled from source, and the database 
(for the shelve) is gdbm. (I can use installer 5b2, but if the problem 
is not in my script, it would be nice to have the next installer version 
without this glitch). The script is as follows:

import time
import shelve
import thread
import commands

def main():
     db = shelve.open('/tmp/test.db')
     db.sync()
     callprogram('main')
     time.sleep(1)
     thread.start_new_thread(callprogram, ('thread',))
     time.sleep(1)

def callprogram(parameter):
     print 'Starting', parameter
     rc, output = commands.getstatusoutput('/sbin/ifconfig')
     print output, rc
     print 'Ending', parameter

if __name__ == '__main__':
     main()

It runs perfectly without opening the shelve, but if it is opened, the 
thread hangs...
