Interesting.  The only detailed docs I can find that discuss this are
for Apache 1.x.  It describes the server-context shared memory as
copy-on-write [1], So I'm not too confident that loading before forking
would really yield much benefit...  Unless we were to slurp in all the
templates at startup, which is an interesting possibility.

I suppose we could explicitly use the Apache server-context memory pool,
but in either case, the real question is still what to cache.

Pete.
