Ah yes, I missed that. Removing that waveshape does indeed seem to stop 
the hangs.

I've also found the cause of the problem which has been giving me 
problems for the last 3 days. It seems that if LiVES starts audio 
playback using sox whilst the listener is active, then the listener is 
never released properly. So the next time an actor is inited, the new 
input fails and causes LiVES to crash.

It took me a while to figure out what was going on, but now I've fixed 
the problem in LiVES by always initialising generators _after_ audio 
playback starts. I'm guessing when sox starts playing it resets the 
sound card and messes things up. All these problems should go  away 
if/when I get to implement the internal audio player for LiVES (planned 
for early next year).

Anyway, the latest CVS build seems very stable, provided arena is 
removed from gforce. Just a couple of very minor issues which I'll try 
to fix next week:
 - 'x' (swap forgeground/background) does nothing after a modeswitch 
(ctrl-number,'k','m') : workaround - switch any transitions off and back 
on again
 - 'k' (grab keyboard for last effect on) sometimes seems to forget the 
last effect on after an effect is switched off
