Good point; that should be fixed.

Hmm... maybe we can dispose of the PROT_* argument that way on Unix.
But how would you specify MAP_SHARED vs. MAP_PRIVATE, or
MAP_ANONYMOUS?  (MAP_FIXED seems useless to a Python programmer.)
Another character in the mode argument, or a flags argument?

Worse, as you pointed out in the same thread, MAP_ANONYMOUS on OSF/1
doesn't want to take a file descriptor at all.

Also, the tag name on Windows seems important, from Gordon McMillan's
explanation of it:
