 Another bit of information of interest: sending the process a kill -stop 
 (-17) after trying to stop it with ^Z *will* cause the process to stop.
 
 Sending it a kill -stop without hitting ^Z will also cause the process to 
 stop normally.
 
 In either case, however, resuming from the shell with fg will cause the 
 same infinite-loop behaviour.  Resuming with a kill -19 will also cause 
 the infinite-loop behaviour.
 
 Sending a regular kill signal also causes the infinite-loop behaviour. 
 The process has to be killed with a kill -9 in all cases once this 
 behaiour starts.
