just multiply suggestedTableSize by 2.

OK, then this is probably a bug. I guess someone will have to look into
it. Personally I'm not so much interested in doing that ATM.

I'm pretty sure the boot loader doesn't do any cleanup at all. If after
some error it returns to the OF prompt, the only safe thing to do is a
reset. If you mean you encounter the problem after a reset, then this
sounds more like a OF bug.
