#580726 comes from the ptrace thing I mentioned. I identified the
commit that makes it fallback to ptrace for firefox case, while it
seemed to work fine before without fallback, and then there are issues
in that ptrace codepath that might have always been there, but they
just didn't get hit due to ptrace fallback being much rarer before
this. I believe the commit hash is mentioned on the bug.

#578582 seems to be just patrick being special and refusing to provide
any information about the bug that no-one else hits.

Maybe if we revert that more easy ptrace fallback stuff for now, the
rest in sandbox git master is fine (if my opendir fix gets applied
that's only patched in via ebuild right now)?
