so you don't have to bother recompiling them on startup if they
haven't changed.
Petal does that as well.

AFAIK TT doesn't precompile templates, it caches them on first use.
Which means you'll take the hit in each forked child unless you
explicitly precompile them. But perhaps I'm wrong about that?
That is probably right. Petal behaves the same way. You usually
have to call them, either as a request or some other way.
I opted for 'some other way'-- i just find and loop through all my
templates on startup as dummy documents.
Here's what i do in startup.pl:
a- i patched petal to not die and still compile the template if not
given the right hash info (its was put in the last version )
b- i do a recursive loop on my template dir to find template files,
then make blank dummy templates
originally i did this with File::Find. Then i found out that
File::Find is gigantic-- 2+ MB. ModPerl::Utils's unload couldn't get
rid of enough of it for me. so i just did a dumb recursive loop.
not as fancy, but its a fraction of the resources.
i included the code below, as i think its of marginal use to others.
FindMeOn::Templater is just my webapp specific template base class,
that wraps Petal or whatever else engine, hold some defaults, and
gives a standard interface.
