--- Comment #22 from Xavier Hernandez <xhernandez at datalab.es> ---
If enabling only PROT_EXEC without PROT_WRITE does not trigger the selinux
check, maybe we could change the way it's done. For example we could mmap only
with PROT_WRITE, generate the code and then change the protection to only
PROT_EXEC.

That would require considerable changes since the current implementation uses
the same allocated memory to create multiple dynamic fragments of code as they
are needed. We would need to have a single mmap() for each fragment of code.

What do you think ?
