Re: memory leak

[Daniel Wheeler]

It's using a number of extension modules:
    scipy
    Numeric
    pysparse
These are all c extensions and could all be leaking memory 
independently of course.

However, I would like to understand first if pure python can leak 
without the reference count increasing?

sure.
For example:
for i in range(N):
        print ref_count_all_objects()
        do_something()
and every iteration the ref count is constant but the memory usage is 
increasing. What are the
likely problems?
leaking extension modules?  it's pretty much impossible to say, without
knowing more about "do_something".  what does it do?  what kind of
Python modules is it using?  what extension modules are involved?
