[Tutor] memory checking

[nik]

hi,

I've got a c++ app calling python functions - are there any way I can 
check for memory problems (leaks etc)? Previously in my windows days 
I've used Boundschecker or Rational Purify, but now two things are 
different a) Python is in the mix, and b) I'm on linux - any advice 
would be helpful.

My main concern is I'm not fully confident I'm using the Py_INCREF and 
Py_DECREF effectively - I know when I'm decref'ing at the wrong places 
as I end up with ref count 0 objects (and crashes), but I'm probably 
overly incref'ing - obviously I'd like make things a bit less hit or 
miss than that!
