I'll try to explain what I refer to as 'caching'. When the engine loads
a template file, it needs to parse through it and construct an
intermediate in-memory representation. When you later assign variables
and do tmpl_fetch(), it walks through this intermediate representation,
filling in values, looping sections, etc. and then returns the result.
So, unless template file changes on the drive, it's not necessary to
have the parsing stage done each time and thus this intermediate
representation can be cached in memory so that only the second stage is
necessary each time.

I see that you want to actually cache the template output for some time.
I suppose we can allow for that, it'd have to be a separate setting that
says how long to cache the template output for. Since we'd have two
kinds of caching, I'm not sure what would be good names for each one
then.
