I certainly wouldn't mind a top-level user-only/ or posix-only/ in which we could share
code between {linux,bsd}-user/, but I don't have a good idea of what that would look like.
Already you have code for MAP_EXCL that doesn't exist for linux (though there is a new,
related, MAP_FIXED_NOREPLACE, which linux-user/ does not yet support). So even with
"obvious" routines I'm not sure how much real sharing we can get away with.
All I can say is: patches welcome, and we'll bike-shed them as they come.
