I stopped Evolution (just the main program, not all the background
helpers) and this caused the CPU/Network IO for evolution-calendar-
factory to go back to normal (it stayed running).  After starting
Evolution again, I still have the same evolution-calendar-factory
process but the CPU/NetworkIO has stayed nominal so far (5 mins).

So, whatever it was that was going on is being instigated in some way
by the evolution binary.

It doesn't seem to happen too often, although maybe it does and I'm
just not noticing it; I have to be checking my network monitor.  Maybe
once every week or two?  If/when it happens again, is there something I
should do to get more info in the moment?
