Comment (by igaztanaga):

 Vicente confirmed Mac Os 10.7 also passes your testcase successfully. I
 think the correct solution would be to detect the minimum Mac Os
 requirements for the build, checking the value of
 MAC_OS_X_VERSION_MIN_REQUIRED. Something like:

 {{{
 #!cpp
 #if defined(__APPLE__)
  #include "TargetConditionals.h"
  //Check we're on Mac OS target
  #if defined(TARGET_OS_MAC)
         #include "AvailabilityMacros.h"
         //If minimum target for this compilation is older than Mac Os
 Lion, then we are out of luck
         #if MAC_OS_X_VERSION_MIN_REQUIRED < 1070
            #define BOOST_INTERPROCESS_BUGGY_POSIX_PROCESS_SHARED
         #endif
  #endif
 #endif
 }}}

 If the SDK targets for Mac Os Lion or newer, then native process-shared
 mutexes will be available.
