I think this is acceptable overhead;   I would like to have an option to
turn off the astral planes if possible.

If you are up for it, I would love to support the 4.0 code as well, as
our next release will be a big push for 4.0 support (this will be our
new default).

Is your Linear + bi-level patch available in Bugzilla?
