Tops10 is also "special" in the way that the
user jobs VM
handler is merged in to user space if needed.. -:)
That's true - under TOPS-10 you can actually write your own page fault handler. The
idea was that, with knowledge of the application, you could write a more efficient paging
algorithm. Don't think that actually happened much (if ever!) though.
A couple of us did once have a contest to see who could generate the most page faults
per second by writing the stupidest possible page fault handler.
