window: Use a persistent, big shm pool during resize

The biggest performance bottleneck while resizing is the continous
setting up and tearing down of mmaps and faulting in pages.  This commit
introduces a per-window pool that we'll allocate buffers out of if it's
available.  Then we set initialize it to a big shm pool when we start
resizing and free it when resizing is done.
