You're welcome!

No, and I _do_ think it's a very serious issue.  You can build Python
with various switches to get more information on memory behavior, but
I've never found that to be a really satisfactory alternative.  A
"footprint profiler" that is able to trace where and roughly how much
memory is being spent/tied up would be a real boon.  The functions
get_referrers and get_referents of module gc do help, to some degree,
but it still seems to me that we're way behind in this task.
