Does it work if I Forbid() and then page fault?  Disable() and page fault?

(i.e. if my Forbid() gets broken and whatever I was trying to mutex with
the Forbid() gets un-mutexed, then it don't work.)

I've heard of GigaMem, but I'd be interested in seeing exactly what
restrictions are placed on programmers because of it.  I am writing a
shared library, and I don't want to deny appliction programmers use of
my library if they want to use GigaMem.
