I'm late to the party, but i've always wondered why we have all these 
different "insert_<foo>_catchpoint" and "remove_<foo>_catchpoint" 
functions to accomplish tasks that seem to be very similar in nature.

Not saying we should go this route for this patch, but we may want to 
consider a more generic RSP packet for catchpoints. Something like the 
following:

QInsertCatchpoint:[syscall|fork|exec|vfork|unload|...]
QRemoveCatchpoint:[syscall|fork|exec|vfork|unload|...]

... or even communicate catchpoints through Z/z packets, though that 
would be a more radical approach.

Anyway, just throwing a few ideas since i've been dealing with some of 
the issues with catchpoints, forking and gdbserver as well.
