Okay.  That means we do need two kinds of critical sections, then,
because the crit sections I've just sprinkled everywhere are not that
critical ;-).  They just want to hold off cancel/die interrupts.

I'll take care of fixing what I broke, but does anyone have suggestions
for good names for the two concepts?  The best I could come up with
offhand is BEGIN/END_CRIT_SECTION and BEGIN/END_SUPER_CRIT_SECTION,
but I'm not pleased with that... Ideas?
