Summary: sdcdb hangs if child s51 process turns zombie

Initial Comment:
During a debug session with sdcdb the spawned s51 process 
stopped responding, this in turn had the unfortunate effect that 
sdcdb allso hangs without any error messages.

Going through the code in the function openSimulator (simi.c) it 
seems that the socket is opened correctly for read and write on 
the appropriate port. In turn sdcdb waits on output from s51 in 
waitForSim (simi.c) - since s51 is not responding this never 
happens.

The arguments of waitForSim suggests a timeout, but this isn't 
implemented.

I've tested with sdcc 2.5.0 (#1020) and 2.5.1 (#1028)

Message:
In SDCDB 0.9 I think you can still use Ctrl-C.
In revision #6092 the timeout is also implemented.
