[IPython-dev] memory leak?

hi,
lately I have been using ipython to %run scripts that create large
numeric arrays (in my case say 1000x1000 complex numbers). The problem I
see is that when I rerun the script its like all variables created in
that file are not freed even though if they have not been accessed in a
way that would put them in the In or Out cache. For instance %running a
file containing
import Numeric
a=Numeric.zeros((1000,1000),"D")
repeatedly without any intervening commands will have memory usage go up
with every invocation of %run. But using execfile from an ordinary
python prompt on the same file this is not the case. Is this a known
problem (I'm on windows)? If it is, is there some way to manually free
this memory?
