Hmm, you are (almost) correct. Of course there is no way to ignore thread's
stacks when counting VM size ;) I just compared what task manager show in its
"VM size" column with SysInternals's Process Explorer (wich i used for a long
time instead of TM). PE show VM size correctly and what TM name as "VM size"
is a "Private memory" by PE.

So, you are correct that TM show VM size wrongly. But i was correct also
when i said that you saw not a VM size ;) And of course reason of "unable to
allocate memory from operating system" error message was out of virtual
address space.

Vlad
