We owe users at least a message saying that we are gathering info/fonts or
whatever, and that that might take a while.

It is always a UI bug that Emacs seemingly does nothing - seems to hang, without
forewarning users or providing progress info.

The user who reported this even went to the trouble to try to track down what
was happening.  This kind of heads-up from a user should be a wake-up call, not
just an excuse to close another bug.
