FWIW,

The issues I pointed out are still standing:

- It is yet undetermined what the performance effect will be, and it is not clear (but seems likely from past measurements) if there will be a performance hit even when ASLR is off.
-Apparently there are applications that will segfault (?).

I wouldn’t object to see it in the tree though: it has obviously been the result of a lot of work and it is configurable and well integrated. It will certainly have to be some time in the tree and undergo extensive testing before turning it on by default though so it sounds reasonable to bring it in but leave it initially inactive.

Pedro.
