Comment (by mmoll@…):

 I see that Drew gives two reasons to get rid of the boost dependency:
 - It breaks his code.
 - Boost is a large dependency.
 Neither seem like a very compelling reason to get rid of Boost, esp. since
 Boost is already compiled for everything but OS X 10.10 and is used by
 many other ports (i.e., many users are bound to install it anyway). Can
 you say more why Boost / thread-safety makes your libraries broken?
