It seems to, yes*

*There seems to be a separate regression causing mscorsvw.exe (from .Net 2.0)
to sometimes hang. It's most notable when running winetricks-test dotnet. I'm
attempting a bisect now (running it in a loop 10 times), to see if I can
pinpoint the cause of that. It's notable that this hang occurs after doing
`winetricks vcrun6 msvcrt=native`.
