Did you notice a fixme:ole:FreeSurrogate stub in the logs? If yes, it's a
pretty easy fix. If not, I'm not sure how to make it called (does
CoFreeUnusedLibraries handle that?)

Alright, it makes sense, but how do we do that? I've read wine's svchost
sources (for reference:
http://source.winehq.org/source/programs/svchost/svchost.c ), but there are a
few things I don't know yet:

   - How is svchost.exe actually started if not by CreateProcess? Is is
launched everytime wine itself is launched?
   - If svchost.exe is not started by CreateProcess how can I pass it
arguments?
   - Also, svchost's arguments seem to be Service names/group names. We have no
services for dllhost.exe/Lol's DLL we're loading

svchost.exe usage is still rocket science to me, I've tried to find docs but
there seems to be very little useful tech info on the interwebs :/
