[Twisted-Python] Newbie reactor.crash()/reactor.stop() question

[James Monteath]

Hi,

I have the exact same problem.  I am using the standard unittest, not 
the one found in Twisted, for the moment anyway.

All my tests work perfectly while using Twisted 1.3, calling 
reactor.crash() vs reactor.stop().  I originally had problems calling 
reactor. stop() with the python unittest framework, until I switched 
over to reactor.crash(). 

I then wanted to run the tests using Twisted 2.0.  The python process 
that starts the unittest will hang after all tests are done.   I can't 
kill the process using a CTRL-C at the command line and must use the 
kill -9 command.

Also, I noticed that the main part of the program does execute the last 
print statement found at:

if __name__ == "__main__":
    run()
    print( "This will print and then hang" )


The following is a bug that had similar behavior, which **may** explain 
the source of the issue:

I am using python 2.3.4 on SUSE 9.2,  and also new to Twisted...

James.
