Note that this patch contains also a cleanup of a useless template
parameter _Is_pod_comparator on _Rb_tree_impl.
The useless parameter is a remnant of an attempt at exploiting the EBO
for _Rb_tree_impl. At some point Benjamin got a patch from a contributor
but then had to quickly revert it just in time for the ABI freeze
because it didn't work. Evrything is recorded in the mailing list.
Anyway, whatever we do now (more exactly, post 4.9) let's make sure we
don't break the ABI inadvertently, or, if we actually decide do that, we
should reconsider the EBO.
About the node recycling idea itself, we got a closely related Bugzilla.
Is it *exactly* the same issue, or not? Please double check.
