Try this (already committed to CURRENT as rev. 1.579). I would be very
interesting in getting feedback.

Konstantin,

thanks for your help.

The patch below *appears* to have helped.

The server survived for more than 24 hours under heavy (mysqld / apache)
load.

Previously, it would not typically survive this test for more than 5
hours.

It's difficult to be 100% sure as the server load is not reliably
reproducable.

I will keep you informed of any developments.

Thanks for your help.

Kind regards,

Good. I MFCed it today as rev. 1.516.2.9 of amd64/amd64/pmap.c.
