I just ran a test on my Windows machine with all of the effects settings maxed.
 I had Task Manager up on another screen.  There was no evidence of any memory
leak.  The memory usage stayed around 1.3GB throughout a several-hours long
lame.

If there is a memory leak in SoaSE, it is being triggered by Wine, because it
just isn't happening on Windows.

I am using wine 1.1.12 (RPM) on Fedora 10 64-bit.  My PC is an i7 with 6GB RAM.
The vid card is a NVidia 9800gtx+ with 1GB video RAM.

When the effects settings are maxed-out, my games last less than 5 minutes
before getting the GL_OUT_OF_MEMORY error.  It is hard to believe that whatever
leak is going on is eating up 1GB of video RAM that fast!

I am running the latest version of SoaSE.  I just updated it yesterday
(2009-01-16).  I can't find the version number anywhere, so the date is the
best I can do!

Below are the first few lines of the Wine output after the failure.  I trust
they are the same as what everyone else is seeing.

fixme:d3d_surface:surface_prepare_system_memory >>>>>>>>>>>>>>>>>
GL_OUT_OF_MEMORY (0x505) from glBufferDataARB @ surface.c / 1031
fixme:d3d_surface:IWineD3DSurfaceImpl_LockRect >>>>>>>>>>>>>>>>>
GL_OUT_OF_MEMORY (0x505) from glMapBufferARB @ surface.c / 1178

I have not yet tried the surface_prepare_system_memory workaround patch.
