Which illustrates how this can be fixed, actually.  The simple way is 
to change BitmapIndex not to pass through its other __new__() 
arguments; it really doesn't need to.

I would recommend this as the way to fix this problem, as it doesn't 
incur any performance overhead; in fact, it should improve 
performance.  It does require changing any class that has the 
problem, but there shouldn't be very many that suffer from it.

I just went ahead and checked in a fix to PEAK-Rules for this, since 
it's clearly the correct solution in this case.

It's possible there are other projects of mine requiring similar 
fixes (likely Trellis and Contextual), but they can be fixed on a 
one-off basis.  I'm not 100% certain as yet that changing AddOns is 
the right/safe thing to do, so this is what I'm going to recommend for now.
