[ZODB-Dev] Max requests for ZEO Server

hi,

on a related note, I am would like to know if there is any point in
deploying the ZEO server on a multiCPU machine, considering python's Global
Interpreter Lock. I suspect not, since I would have to bind the ZEO to one
processor to avoid the problems with the GIL in multiCPU circumstances,
right?

Thank you.
