thread not responding

["Mark M. Ito" <marki@jlab.org>]

D Listers,

I made a change to allow my fitter to attempt to fit events with a more 
challenging configuration than before. No doubt this is exposing some 
pre-existing bug. The failure mode is apparently that a thread is not 
reporting signs of life soon enough (see transcript below). Have you 
seen this before? Does this mean I have an infinite loop in one thread 
or another? Is there a way to increase the time-out period? Have never 
dealt with threads so am a bit confused about how to proceed with debugging.
