good analysis! :)

But allow me one remark:

You should use "use strict" and "use warnings" even in such a test 
snippet.

With this your script stops here:

>  local $tmpl = MT::Template->new;

I guess you mean "my" and not "local"; see "perldoc -f local".

Perhaps this makes a difference at this test (not tested)?

hmm, but then every piece of code which uses MT::Template must be 
checked. It would be better, when MT::Template does this by itself by 
adding a DESTROY method, which should make the big cleanup. [1]


BTW: There are also Modules on CPAN which helps for searching for memory 
leaks, e.g. Devel::Leak and Devel::Leak::Object


Ciao

DESTROY gets called when the object gets out of scope, see "Destructors" 
in perldoc perltoot.
