You could do something like:

gcc <blah> | tee <output-file> | grep -El <regexpr that finds errors>

...which would return relatively quickly if an error is found, otherwise 
will run to completion. (Note: especially using tee, I'm not sure what 
will happen when grep exits, i.e. if tee and/or grep will die or not, so 
I would suggest testing, and invoking 'kill' if needed.)

Why not just make a system that fires off a submission in a separate 
process whenever one arrives? Assuming you have a way to collect a 
batch, I don't know why you couldn't submit them in parallel, but why wait?
