TID 0061 has a lot of d3d warnings, so I assume it's the main thread, or the
rendering thread? I'm not too well-versed into how games are coded.

Anyway, I have these d3d settings:

[Software\Wine\Direct3D] 1322029591
"DirectDrawRenderer"="opengl"
"Multisampling"="disabled"
"OffScreenRenderingMode"="pbuffer"
"PixelShaderMode"="enabled"
"UseGLSL"="disabled"
"VertexShaderMode"="hardware"
"VideoMemorySize"="1024"

I've attached the output after running with
WINEDEBUG=err+all,fixme+all,warn+all,+tid

I initially suspected it was ALSA (as the sound would loop when it freezes),
but   I built this version of wine without ALSA support (latest Git version as
of yesterday).

The game was run with -nod3d9ex (as we are supposed to for Source games).

I've tried to do a full trace, but it slows down the game too much to be of any
use.  I can fairly reliably reproduce this, and I am a code monkey myself (who
isn't nowadays), so I can maybe help you guys fix this, if someone can show me
how to debug this.
