-1 is no longer an allowed system call.

This treats a nasty bug where forking and exiting before the child causes the kernel to panic, because the syscall -1 is run, which just contains a trash value that happened to be 0. The cause is still unknown. Might be the scheduler. This won't help me sleep at night.
