Comment (by kovshenin):

 Looking at .2.diff. I like the general idea of ajax:start and ajax:end,
 however, the spinner count incr/decr has been moved away from
 updateSpinner and the check for spinnerActions. So in theory:

 * ajax:start could increment the spinner count for query-attachments,
 spinner shown, count 1
 * ajax:start increments the spinner count for an action called foo-bar,
 spinner shown, count 2
 * ajax:end for query-attachments, spinner still shown, count back to 1
 * ajax:end for foo-bar, count is 0, but the spinner is still shown because
 updateSpinner will bail for foo-bar

 In reality though, I haven't found a neat way to reproduce this, but I
 think either way we should keep the action check closer to the spinner
 count.
