| As Lars explained, you definitely want to use _exit() in the child, so

This poses a little problem:  What if a GTK application wants to execute
a program and, say, give the user some buttons to kill the program using
various signals?  That program very well might be using exit(), and thus
screw up your application.

If anybody else with more in-depth knowledge of how this works could
comment, please do!  The ability to run child processes from a GTK
application seems, in my opinion, a VERY important thing.
