This is just an RFC; if other developers approve of this approach, I can
make a more extensive patch removing the use_reusable_pool parameters.
The x11perf numbers below compare ShmGet/PutImage before and after this
change with glamor from keithp's glamor-server xserver branch on a Kaveri
APU. The change also reduces the total runtime of the gtkperf tests from
about 3.5s to about 3s.
