I haven't yet tested this patch. It takes a long time since these are
production machines, and the bug itself takes several weeks of production
use to really show up.

Rik van Riel has pointed out a lot of VM tweaks that he put into 3.4:

My intention is to reboot half of our machines into plain 3.4 once it is
out, and half onto 3.4 + your patch.

Then we can compare behaviour.


Will your patch apply cleanly on 3.4?

Richard.
