Yup. On reflection, that patch has no effect, other than speeding
things up.
However, I think I *have* found the actual bug this time.
Try this patch and report back again.

After first 55 minutes of testing, no timeouts yet, so I'm quite sure it
works ok now (yay!). Without this patch, timeouts happened every couple
minutes on similar load. I think I'll let it run for a day and report
back tomorrow how things are by then.
Note that I didn't apply the previous patch as they don't apply on each
other. If needed, I can test it separately after running this for a while.
Oh, and thanks for the hard work :)
