Thanks for those suggestions.
I added select() in waitChild() to make sure that it does not spin
unnecessarly. It will timeout every 0.1s (default, can be changed via
self.selectTimeout) to keep a possible GUI alive.
Cheers,
Michael
The reason why waitChild() is implemented as a function and not as a
signal handler is that e.g. vte does not work with that. It installs its
own signal handler and you need to use the reaper object to catch
children exiting.
