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.
