I'm sure the additional parameter will be needed, and it might be pretty
involved. I think the current notion of syslets needs, at the very least:
- a userspace stack and IP to return to after going async
- the completion context when completed async
- a pointer to a return code when completed without blocking
We'll see. I'm working on it.
