It's not fixed, but we managed to make it bearable so as not to lose the
client.

by replacing LoginManager with exUserFolder we managed to bring down the
zope restart time from 5 min (we have a HUGE Data.fs) to 20 secs, and by
installing ZEO we brought down the restart time to between 2 and 8 secs.
By increasing the caching of requests we managed to increase the time
between restart from 15 min to 2 hours. That and a nicely formated
Apache error page for Proxy Errors, for the lucky bastards who happen to
hit the server in the exactly 2 seconds of restart, managed to calm down
the client enough for us to breath.

I'll try the requestprofiler tip Chris gave, but I don't have much hope,
since we use mysql for authentication and the site is authenticated
mostly everywhere.

We are seriously considering droping mysql for postgresql.

	Cheers, Leo
