Everytime from what I've been seeing.
I could understand it if only a very minor
increase was witnessed over subsequent calls
but it's every time the process is called.
I can't see that its any of the surrounding code
because if even just comment out the $template->process()
call and leave everything else the same it doesn't jump.
It's almost like the memory that is being used each time
isn't being detected as "free" because it's not being
reused when the chance arises.

Does it jump by 1.2 Megs everytime you reload the page, or does it only jump
the very first time, and then possibly goes up only slightly on subsequent
requests?

Processes never return memory that they have been allocated to the OS. They
reuse the same memory internally, but you will never see a process decrease
in size. The memory only gets released when the process exits. Since you
are using mod_perl, the memory only gets reclaimed when the apache child
process exits.
But perl will manage the memory internally, so if you undef a variable, that
memory can be re-used by perl for another variable.
But the process will not decrease in size.
