probably: the exception is generated as a result of the thread being
discovered unreachable during garbage collection. If there's no garbage
collection, eg. because the program is waiting for I/O, then the exception
is never raised.
Which brings up an interesting subject: should the RTS start a GC after it
has been waiting for I/O for a certain length of time? If so, how long?
Cheers,
Simon
