I too have used g_spawn_async_with_pipes() and GIOChannel's to spawn 
child processes that monitor USB temperature probes and pipe the data 
back to a main program.  For me it was important that the children were 
asynchronous and independent.  The child processes have no GUI or direct 
user interaction (except through the main program).  I have no problem 
spawning multiple child processes (for multiple probes) and can easily 
stop them at will by sending them a signal along the pipe to close them 
down.  The code is very similar to Eric's, albeit buried in a much 
larger program.

I haven't used GSubprocess either but in looking at it, it looks pretty 
interesting.
