This is from evolution-mail.

It _looks_ like lots of contiguous, equal protection mappings which
should be
merged:

So the maps are slowly splitting up even though the permissions are the
same.

It seems to keep growing over time but Evolution isn't 100% stable yet
so it
crashes for no apparent reason every 6 hours or so.. unless that could
be when
it hits some 'limit' on the number of mappings allowed?
