Well, mfind is a routine that finds the ``core map'' entry (if any)
for a particular block on a file system.  pagein will panic if you
get a page fault on a text page, mfind finds it in the core map, but
the core map entry says that it's not a text page, that it's not
``gone'' (i.e., hasn't been freed), or that it's not free.  Why any
of those should happen I have no idea. . . .
