Good question. I'm trying to fix Sorcery Jokers (trial) issue, bug 43119.
The application repeatedly trys to allocate virtual memory as much as
possible, and measures available memory size by GlobalMemoryStatusEx().

This patch is better than nothing. The application stops memory
allocation about 384MB (0x17ffffff) free. After the allocation, it
succeeds to load libGL.so. However, it shows driver pointer missing
error when loading DRI driver, radeonsi_dri.so. I'm still in trouble
with this point.

By the way, I have another idea about this issue. That is reserving
virtual memory area when loading wined3d.dll and release it just before
loading OpenGL libraries. Being hackish idea, I chose the forementioned
method in the beginning.

What do you think about these ideas?
