You keep saying the LoopingCall stops.  It does not stop.  It is waiting 
for a result.  If you provide it with a result, it will proceed.  Glyph 
suggested a number of (hackfully) mechanisms you might use to provide it 
with a result.  I suggested another way (fix the broken code, or at 
least supply enough information for someone else to fix it).
