Thanks for testing. Since the patchset doesn't work properly in your
environment, I can't help withdrawing it.

I saw the message when initial virtual memory size is not enough. So, I
guess the game fails to allocate texture memory due to lack of virtual
memory. Should we reserve some memory areas for textures? How
much is it enough? Another idea that solves this issue is also welcome.
