My guess was that we were trying to save after clearing the cache
because (due to a race condition) we didn't realize we had something
waiting to use the cache. However, that doesn't seem to be the case.
The timing just seems off: we save 10 seconds after changing, but
clear after 120 seconds. I don't really see how it's being hit,
something somewhere is being bad.

In either case, the userInfo for the NSTimer doing the detached save
is being passed as nil, so it ends up saving badly. *myGlobalPrefs is
nil in the preference container.
