Wow, that was even more complicated than I imagined, with lots of
potentially platform-dependent functionality (fork/
background process/kill/sleep ....).

The case I thought about as most tricky to test was to send the
signal (Ctrl-C) while Cons was *not* running another command (via
system), ie. when Cons was running its own code.
When I tested this manually I added a "busy-wait" loop to the Cons
source, but I guess it has to be done another way to be usable as a
real testcase. Can a [perl] rule be used, or isn't that realistic
enough ???
