This blog post was one of the original reasons why I started to write this wrapper script. But thank's for the hint, I will get in touch with him.

Sure. I am going to write some (more) unit tests for it.

I don't know for sure. The current implementation uses threads to monitor the spawned subprocesses. So I'm not very confident I could come up with something similar which then also correctly responds to signals.

Maybe I could try to port it down to Python 2.4. However I noticed that Python 2.6 comes even on my stripped down Opensolaris zone by default. There are some dependencies to a python on this system. Also, Python 2.6 makes it much easier to work with subprocesses.

And as far as I know Python 2.6 will come by default on the next stable Opensolaris release 2010.03. I don't know about older releases though.
