While this might allow the games to start, won't such approach break
(some of) game mechanics or sync with servers? The games might be using
this instead of GetTickCount(), having the time updated at some rare and
irregular intervals looks scary.

I thought that somewhat potentially better approach than that currently
in Staging would be to map user shared area to wineserver and always
create a single thread in server to update the shared area. That would
be somewhat similar to what Windows does if wineserver stands for
kernel. I also heard that sharing memory with server is considered a no
go, but I could not find any discussion why is it so.
