Comment(by AntiCat):

 Your patch did not produce any additional output on my system. So I also
 addad an else statement to doublecheck if the debug output was working.
 Result:
 {{{
 ...
 2009-01-14 10:56:01.602 Allocating a 3844 byte PES packet successful
 2009-01-14 10:56:01.603 Allocating a 3844 byte PES packet successful

 2009-01-14 10:56:01.606 Allocating a 3844 byte PES packet successful
 ...
 }}}

 I alterd the patch a little bit to also catch the other memory
 allocations. Result:

 a lot of allocations but never a free
