I can definitely see the benefit to a more generic solution. I'm not
opposed to it in principle.

Unfortunately, I'm probably not the best person to comment on the pros
and cons of your patch versus the one I'm pushing. My skills in C++
are pretty poor. I'm mostly acting as a liaison and steward for these
patches. I'm trying to facilitate allowing Passenger to compile
against a non-forked version of Boost. To do that, there's a few key
elements of their fork that need to be merged into the upstream Boost.

So, the sooner I can get movement on this, the better.
