Comment:

 Is this at all related to #703?

 I have no idea what SELinux "enforcing" mode does.  It looks like SELinux
 doesn't like us using mprotect() to make dynamically-allocated memory
 executable.  This is required for things like 'foreign import "wrapper"',
 because we have to generate dynamic code.

 It's possible we could mmap() instead, I suppose.

 Can anyone shed any more light here?
