you could modify the entry into any of the gemdos/bios/xbios traps (see
osbind.o) to check for ^C. in this way, when any system call was made, a check
is first performed. this is not really equivalent to signal(3) under unix, but
is better than what's there now. MWC has a signal(3) function but i don't
know how/if it works. alcyon's does not seem to work.
