EXA: Defragment offscreen memory.

At most once per second, under the following circumstances:

* We can't satisfy an offscreen memory allocation, but there seems to be enough
  offscreen memory available in total.

or

* The server has been idle for at least 100ms, and there is more than one
  available offscreen area.
