Ah, but I have this enormous program and somewhere, somehow,
it is locking up in a loop. If I went around putting in
timeouts & traces I'd take longer than modifying the source
for the interpreter and recompiling it and using a ctl-C or
whatever. No, what I *need* is a way of getting the
interpreter to enter its trace routine from keyboard use
and not from trace(). Even then it is a problem because it
is likely the program is not looking at the keyboard, so
the interpreter would have to go check the keyboard itself
for a break character.
Apart from all that, it is likely that the loop is not supposed
to be a loop anyway, so I wouldn't know to trace it.
This is the ultimate cock-up cracker. I could use the profiler
if I could get the program to stop cleanly rather than saying
"This program is not responding - terminate anyway (Y/N)" 
which dumps anything it had available into a black hole.
So thanks anyway, but - I need to ask the question again.
