Subject: Exception handling question...
Precedence: bulk

I'm confused about why it is necessary to lock memory used by an
exception handler.  In the case where code resides in a currently
paged-out location in memory, wouldn't a page fault occur and resume
exception handling properly (assuming that the interrupt flag isn't
cleared.  Or is the issue just that certain exceptions are generally
extremely time critical?
