Wow, I'm actually one step ahead for once:

*Anything* would be unstable over NFS.  Many server programs won't even
start using an NFS partition.  In fact, we should probably change Zope
to sniff and see if NFS is involved, then refuse to operate, lest we get
blamed for the Nightmare File System.

With ZServer you can crank the process up manually.  I imagine that PCGI
will eventually go that way as well.

That is the saddest litany of woe I've heard since, well, three weeks
ago when our ISP screwed us :^)

I don't think that my ZHP information goes in too deep on system
resources.

Ahh, so you've found it.  :^)
