I think it would be OK to assume that services.exe is started by
wineboot and is always running, since we'll have at least the mountmgr
service running all the time.

That's gcc-specific syntax, it would need some #ifdefs.

I'm not sure that is a valid assumption, as we could have an option to 
disable wineboot in the future due to performance reasons.

Well spotted. I'll fix that.

I don't think we want to support that. On the contrary, we want to move
more of the startup processing that we currently do for every process
into wineboot, so that it is done only once per session. This requires
that we can guarantee that wineboot is always executed.

We may of course make some of the more expensive parts of wineboot
optional, but starting services.exe shouldn't be in the expensive
category (and if it is that should be fixed).
