Log Message:
Revamp the NetBSD/usermode pagefault and illegal instruction handing. It now
can handle recursive entry and is a lot more memory tight compared to the old
implementation. Performance wise:

* slightly less number of syscalls/sec possible though could be optimized
* a lot faster context creation / destruction making overall operation faster.
