Re: [igraph] memory owerflow

[Gabor Csardi]

Lubos,

I'm not very familiar with the Python interface, 
but this seems to be either 1) an igraph memory leak or 
2) Python not doing garbage collection frequently enough.
(Or both.)

You can try to call collect from the gc module, that forces 
garbage collection. (At least this is my understanding of the manual,
I cannot try it now, sorry, maybe later today.

Best,
Gabor
