The secondary thread seems to be still blocking in a pselect call when
crash occurs.  Maybe SIGIO (and SIGALRM) should be unmasked in the
secondary thread that calls pselect for keyboard input, and the main
thread should forward the delivery of these signals to the secondary
(or mask them) so that the pselect call in the secondary thread can be
interrupted.
