Unfortunately, exit() is often harmful in C++ programs, since the global & 
atexit destructors are run, but the stack hasn't been unwound so objects in 
the main() function continue to exist. This breaks a number of assumptions 
about the order in which things are destroyed (namely, that it is the opposite 
in which they were constructed).

Using _exit() might help, but it may bring its own set of problems. At least 
it's closer to the qFatal call that is there now.
