I asked this question a few weeks ago and filed a feature request:
   https://svn.boost.org/trac/boost/ticket/6991

There is a patch attached to the bug report which seems to work for me, 
however, you of course will have to use a modified version of Boost. 
(And it's a compiled library so more than just header changes as well.)

I don't know the best way to get that option from the client code down 
to where it's needed, so right now choosing that behavior or the default 
one is done by changing the Boost code and recompiling. :-)

(Incidentally, from my biased perspective I'd say that the fact that 
there were two independent requests for this feature inside a month, not 
to mention the old one linked in the quoted post which sites another a 
couple weeks prior to *that*, speaks to the importance of this feature. 
I'd like to reiterate my offer to help with any of documentation, tests 
(if someone can sketch out how to add one), and implementation (if 
someone sketches out a high-level implementation).)
