Macro names should be all uppercase and start with BOOST... How about 
BOOST_MIRO_JURISIC_AND_PHILIP_KOCH?

Jokes aside, I think that we should postpone this decision until after 1.33 
is released. Maybe even #ifdef on __APPLE__, if you insist.

Are you sure that keeping a reservation alive for extended periods of time 
does not incur a performance penalty, BTW? Could this be the reason for the 
preliminary technical note?
