OK, I will be out of town for a few days, so it would be nice if Corinna 
could apply it as well.

Regarding your remark, I had thought of putting prefix on the cygheap,
but that looked like overkill (could be done some day, together with 
cygwin_user_h and a few others).

With a few exceptions (e.g. utmp/wtmp handling in login/logout), shared_name
is only called when the map handle is NULL, e.g. when starting cygwin 
(thus relatively rarely).
It's also called for the title_mutex, but that's only needed for old systems 
that don't have GetConsoleWindow, so a better optimization would be to only
call it when needed. That mutex is a great DOS source. Fixing that is on
my todo list, as a side effect of more important stuff.
