 The first time I press Keep on a new or resumed Write document, it takes
 about a second.

 Subsequent Keeps can take much longer, and seem to be a function of
 document size.

 Clicking Stop then takes the same amount of time, and doesn't actually
 stop Write.  Oh, sometimes it does.

 By taking time, I mean the button remains highlighted even with cursor is
 moved away, and the graphics artifacts left behind by the "Stop" drop-down
 tool-tip being imperfectly erased are not cleaned up, and clicking on the
 document does not result in vertical-bar cursor relocation.  All these
 then occur together after the pause.

 Started a new document with "fooo" as text.  Keep took less than a second
 the first time.  5-6 seconds for the next three.  I then added more text.
 About 100 characters.  Two keeps both took 16 s.  Removed ~1/2 the
 characters.  Two keeps both took 11 s.  Removed text back down to "fooo".
 Keep 5 s again.  "fooo" spread over 4 lines takes the same.

 A sparse one-page document is consistently taking 27 s to Keep, and the
 same 27 s to (unsuccessfully) Stop.

 But it's all not that simple.  Sometimes Stop works after the delay.
 Sometimes a string of Keeps continue with the short initial delay, before
 transitioning to the long one.  I've not seen a long->short transition.
 The first fast Keep seems independent of document size.
