Comment(by santtu):
As a side comment and further rationale on using mmap: selinux in fedora
particularly tends to disallow changing heap or stack to executable (using
mprotect), the only more-or-less guaranteed working way is to use mmap
(with MAP_SHARED -- even MAP_PRIVATE will fail if allow_execmod=0).
