The fork and execve works now, but unfortunately, it still has not
solved my problem. What happens now is that if I make the parent
process waitpid, then the parent goes to sleep, and the children keep
running, with the application update happening successfully, but I
can only tell because I can see the console output. The children
never get the UI back, and the parent is still sitting in the task
bar at the bottom, but since it is asleep, I can't interact with
it. This leaves me in what is effectively a deadlocked
situation. Its some progress at least :)

I tried using execve, but I always get a ENOTSUP returned from

execve() will return ENOTSUP if your process has more than one
thread. Forking will fix this, though - try something more like...
pid_t p = fork();
if(p < 0)
{
scream_bloody_murder();
return;
}
if(p == 0)
{
execve(whatever);
}
exit(0);
