Features We Do _Not_ Want
=========================
* All backends running as threads in a single process (not want)
This eliminates the process protection we get from the current setup.
Thread creation is usually the same overhead as process creation on
modern systems, so it seems unwise to use a pure threaded model.
* Optimizer hints (not want)
Optimizer hints are used to work around problems in the optimizer. We
would rather have the problems reported and fixed.
