"Interesting" choice - oh well.

I had hoped to be able to test and commit today, but I'm too beat from
the trip from Canada to be able to do this until tomorrow (it's very
high in the priority list to get this done tomorrow but I don't know
how hard the jet lag will hit this time).

I haven't seen enough reports of this patch working to be really
comfortable committing the patch without having had a chance to try it

Other people who try this patch please report any success/failure.
Success can also just be reported in private mail.

Oh, and in case people were wondering - I'm not a "vendor branch
purist" wrt. OpenSSL, so getting the patch commited once I'm sure it
is OK isn't a problem.

Alexander, thanks a lot for looking at this!
