Exactly.  On Linux it would work, because you can use mprotect() to
make even malloc()ed memory executable, but I doubt this non-Posix
extension works on cygwin.  What might work instead would be using the
Windows API instead of the POSIX one.  In pypy/rlib/rmmap.py, look for
"def alloc" and "def free": there are the two versions.


A bientôt,

Armin.
