Comment (by Github):

 Refs #9682. This creates a runnable that updates the free space list on
 the master backend.

 The problem with the existing code is that if any mount goes dead each
 frontend causes one more worker thread to queue up every 15 seconds. If
 you have 3 frontends 720 threads are started every hour the mount is down.
 This instead uses one runnable to update the total disk space every 15
 seconds for use by all the frontends. If no frontend requests an updated
 disk space calculation for one minute the runnable shuts down.
  Branch:    master
  Changeset: 394c2e82c8723605d939b02a789f068aa8c62d44
