There can be a monitor, but there must not be one.

Yes - It should - This way you can handle syscall in the RTHAL domain
und substitute it with you own syscall, doing the same, but better then
linux (e.g. nanosleep).

Or the syscalls to the nucleus and skins, they are completely handled
outside of the linux kernel.
