This is probably related to our kernel64 hack..

-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.
