here is my understand and please verify.
say i have sub parse { return
$array_ref_contain_the_data }
does that memory used by the
$array_ref_contain_the_data can be reused by other
mod_perl application too? or it is used only by the
particular $array_ref_contain_the_data?

even if i am using an iterator object and call it.next
in TT, doesn't TT actually keep the rendered template
page into one variable and dump it to the browser? in
that case, the memory consumed is still equal to the
entire size of the data and iterator doesn't help
here. am i right?
