Hi,

I've rebased my earlier patch to fix some minor conflicts with the
work done on bitmaps in December last year. I've also included Andres'
cursor-based isolation test as 0002; which now passes.

This should take care of cfbot's misidentification of which patch to
test, and thus get CFBot to succeed again.

The patches for the back-branches didn't need updating, as those
branches have not diverged enough for those patches to have gotten
stale. They're still available in my initial mail over at [0].

Kind regards,

Matthias van de Meent
