References request_spawn().

int spawn	(	const char *	,
		const char *	descr
	)

Will branch of a new process to execute the provided script. The return value is a local process id of the child.

A vfork should work slightly faster We don't care about a new task structure anyway

If we use exit instead of _exit our own static data structures will be destroyed ! Of course this routine is only necessary when there was an error becoming something else.
