This would mean we'd stop support for RHEL 5, which is probably OK,
seeing that even the super-extended support ends in November 2020.

Dropping RHEL 5 would also allow us to drop support for Python 2.4,
which is something I've been itching to do. ;-)

In both of these cases, maintaining support for all these ancient
versions is a significant burden IMO, so it would be good to clean up
the tail end a bit.
