It would have been helpful if Austin had linked to the bug report
from his patch.  I went and filed a (very well documented :-) bug report
http://bugs.winehq.org/show_bug.cgi?id=12548
that turned out to be a dup of the one Austin had been discussing
the bug in.

Austin's patch is helpful, but I think we can do better.  For instance,
we could ship a helper app that pops up a gui
and asks whether the user wants us to work around the problem
(by doing  gksudo sysctl -w vm.mmap_min_addr=0, say)
and run it in the preloader if we can't map the lowest page.

I had started to notice it whenever ubuntu upgraded the hardy kernel
to 2.6.24. A helper app would be good, but in the meantime, I think a
link to a wiki page with links to the bug #'s, etc would be helpful. I
wrote the patch before your (very detailed :-D) report, however.
