And this doesn't seem to end. Looks like someone forgot to MAP_FIXED, and it
got triggered on RANDMMAP.

RANDMMAP is not particularly useful with Wine, and will break memory
reservation, but most things should still work. What is the actual problem you
are seeing?

Well, i stumbled upon it when i tried to strace wine to catch what's happening
with hanging Space Rangers HD. Somehow strace re-enables RANDMMAP even when
it's disabled for the strace binary itself it seems. Anyway, the problem with
Space Rangers is vanished somehow.

Huh? Is this a correct usage of mmap?

Yes, the goal is to reserve all available memory.
