Too bad two out of the four pieces of advice are wrong (how many pieces
of memory managed by the backend are allocated directly with malloc?).
The other two are not wrong as far as they go, but they're certainly
woefully inadequate, because no interesting backend extension is going
to be able to get along without calling back into the core code.

Personally I would reduce this section to

<para>
Don't.
</para>

I don't think it is worth our time to try to support people who run into
the inevitable memory management and error handling incompatibilities.
Nor are they likely to be happy at the end of the experience, if we
blithely tell them up front that it'll work.
