That just imports the package so it doesn't do hardly anything.

That executes the Template module, which as Tavis said is quite involved.
I'm getting 1.5 seconds to import the module from disk the first time, 
and 0.75 seconds to import it from OS memory buffers thereafter.  That's
with AMD-K6/450 and Linux Debian.

It used to take longer to instantiate and fill templates, but that's
pretty instantaneous now.  So the amount of efficiency we've squeezed in
is about as far as we can get.
