i have a ibm at clone running xenix 2.0. 
suppose i run the following program in the foreground:

 int i;
for (i=0; i<30; i++)
signal(i,(char *)1);
for (;;);

will i have to turn off the computer in order to
have the machine useful again? as far as i know, there is absolutly
no job control on this machine. no way to send any signals from the
keyboard except 2.
i've run a few programs that just seem to hang, and a lot that ignore
int2. how do i abort one?

gwoho liu.
