/* Not entirely sure how I should handle forks/execs etc, mostly whether I
 * should allow forks/execs to be called directly or only though the process
 * manager. Probably though the process manager, although that will add in a
 * slight bit of delay.
 *
 * I suppose I could add in a runtime parameter
 * that would allow them to be called directly, and then the process manager
 * would have to periodically ask the kernel about all threads it is aware of
 * via sys_sync. Dunno.
