[PATCH 2/2] Rate limit pulse() calls to ProgressWindow.

[Peter Jones <pjones redhat com>]

Make the pulsed progress windows only pulse but so quickly.  The net
effect is that the filesystem creation progress window now slides back
and forth (albeit with a little much punctuation) rather than blindingly
oscillating at breakneck speed.
