You don't need threads to run another process "in the background". For
example, here's how you would do it with Twisted:
from twisted.internet import gtk2reactor
gtk2reactor.install()
from twisted.internet import reactor
def main():
reactor.spawnProcess(
None,
'/usr/bin/fluidsynth',
['fluidsynth', '-ni', '/home/mysndfont.sf2', 'mymidi.mid'])
reactor.run()
Your Gtk app won't block and you won't have to worry about the
threading/forking/signal interaction that is messing you up now.
