well, CreateFile() accepts 0 as second argument, which is what we
need-- just query information no matter if anyone opened file in
DENYALL mode. i've just tested it on nt4.0 -- it works fine.

the only question is whether we should add new parameter to
fhandler::open(), say 'int cygwin_flags', or define new flag in
fcntl.h? for me, the first one looks preferable.
