Okay, thanks.

Unrelated nit on patch 3/3:
+    lpmemex->ullTotalVirtual  =
min((ULONG_PTR)si.lpMaximumApplicationAddress-(ULONG_PTR)si.lpMinimumApplicationAddress,
ullTotalVirtualMax);
     /* FIXME: we should track down all the already allocated VM pages
and subtract them, for now arbitrarily remove 64KB so that it matches
NT */

This line is too long, please place the comment on a line by itself.

Thanks,
