Ok, that sounds like you hit a page-fault-of-doom on the fallback path. The
objects are just big enough for it to try mapping both of them at once, but is
unable to fit both simultaneously into the aperture. The result is that it has
to swap both objects in and out of the aperture around every single byte. That
is slow enough for the computer to appear to be unresponsive.

Sigh. It is meant to fallback to CPU mappings to prevent this.
