Assig. 3 - IPC by signals

And I wonder whether a shootout is a form of communication ;-) 

Yes, some primitive form of inter-process communication can be implemented
using signals, but do you really want to deal with suspended signals, stopped
signals, hairy race conditions, etc etc etc?

Signals are really meant to notify exceptional, unpredictable, conditions,
not as a substitute of real IPC primitives. Moreover, the text is clear:
you must use Sys V IPCs, i.e. message queues and/or semaphores and/or
shared memory areas.
