Below is a simple program that will cause python to intermittently

I'd be tempted to say this is a nasty garbage collection performance
issue except that there is no major memory to be garbage collected in

way before the memory if filled. (at about 20% of physical ram). Additionally
the process monitor shows no page faults.
Yes if you let the as-written demo program run to

I think the point you are missing is that the garbage collector is
triggered from time to time to ensure that no cyclical garbage remains
uncollected, IIRC. The more data that's been allocated, the longer it
takes the collector to scan all of memory to do its job.
