yes - it wouldn't kill.   Only the -9 option would kill it.    Like I 
posted earlier,
After identifying the function that hangs up (my putting "print" 
statements before
and after),   we also put a print statement at the beginning of the 
function that
hangs up,  but it never gets called.   So the process of calling the 
errant function
is enough to send it to never-never land.   How does one debug these 
kinds of
problems?
