Personally, I'd rather write if (!(child = fork())) { do_stuff(); execve(foo, bar, baz); } than ram_stuff_into_structure(&foo); child = spawn(&foo); } because the former allows me to do arbitrary stuff between fork and exec, while the latter only allows me to do things the library / kernel designers have foreseen.

As for "And with multiple threads, who ever really needs fork anyway?", how about "anyone who wants to get a useful program-readable error indication when the activity that's just been kicked off corrupts its heap, rather than having the whole kit and kaboodle come crashing down with a SEGV"?
