For the latter: correct.

For the former (use mod_wsgi): I had actually implemented it, but needed
to revert to FCGI, because mod_wsgi would cause too many hanging servers.

As for the switch to WSGI: it will *introduce* new problems.

I disagree that these are small and low-risk. The WSGI switch will risk
stability; the others (generate static pages) will not be small, and
risk correctness.
