what the hell is that ??

Ok, I'll officially hijack the thread.

What exactly determines the size of this process?

It's not hyperthreading either, since I have it on my processor (where 16k is reported). It can't be cores, since the math doesn't add up. I have 2 cores, so two idle threads. Just curiosity, but anyone knows?

I believe the memory used column in taskman is merely the process' working set size, and not the actual memory used, in XP. They may have changed things in recent versions of windows; I don't rightly know.
