as in util/hashtab.h:
// TODO: should probably use boost::bind for this, but didn't want to look at it

and in db/namespace.cpp:
// TODO: need to implement this
// need boost::bind or something to make this less ugly

And I took a little time to look at this piece of code and find it's easy to translate the function callback into using boost::bind.
