I added a GdbStub for a game console emulator on which the actual code 
for debugging is running on. But instead of sockets I used pipe to 
communicate. In this case gdb just sends a ^C to the emulator which 
leads to a SIGINT signal. I just had to wrote a SIGINT handler for the 
emulator to get this working correctly. The handler just sets a Variable 
to '1' and the Emulator checks at a certain point. If it is sets and 
handels control over to the "main" function of the stub where all the 
command processing is done. Not exactly the case you have but maybe that 
helps.
