Yes, that's one of the mmap addresses used by the JIT, if available. More to the point, googling for "fork cygwin mmap" shows that there are open bugs with cygwin's fork() in the presence of MAP_PRIVATE mmaps. That's obviously why it fails. I don't really know what we can reasonably do about that, short of asking people to use some specific versions of cygwin where it seems to work. I can imagine what we could unreasonably do as work-around, but that requires a lot of work and gross hacks that don't seem appropriate to put in the pypy source just to support cygwin... I would recommend that you try to see it fixed on the cygwin side.
