How much memory (and overhead) are we talking about here?  Can we get a
measurement of this?

Clearly, if it were one byte, and one nanosecond, this change would be a
win; if it's 100 kilobytes, and 100ms, it would be a lose.  But the added
functionality does seem useful (after all, it lets us change libs on the
basis of any sysctl node, and most ports expose a lot more MD nodes,
including nodes that could be used to select optimized libraries, than
the loader actually knows about now) and eliminating users of the old
sysctl interface seems like a win, too, since it's deprecated and a
maintenance hassle.
