Description Ted Ross 2009-06-10 13:32:21 UTC 
Description of problem:

If the messaging broker is hung (i.e. the process exists but it it not handling incoming data), establishing a qmf connection will hang indefinitely.

Version-Release number of selected component (if applicable):

1.1.1

How reproducible:

100%

Steps to Reproduce:
1. Start broker interactively
2. Pause broker with control-Z
3. Run qpid-config (or any other Python-based tool)
  
Actual results:

The command will hang until the process is restarted (with 'fg')

Expected results:

The command should fail with a timeout error after some finite time.
