---------------------------------------------------+------------------------
 This issue only exists explicitly for OSX leopard 64 bits application
 trying to use IPC.

 Windows 32/64 bits, XP, Vista, Win 7 has no issue and
 OSX 10.4: 32 bits, 10.5: 32 bits, 10.6: 32/64 bits all works fine.

 The issue is due to "inline void get_bootstamp(std::string &s, bool add =
 false)" function.

 When a 64 bits host application create the shared_memory_object, there
 will be a folder somewhat like "33FABFC2B8FACA0133FABFC2B8FACA01" being
 created in the boost_interprocess directory.  When the 64 bits client
 application trying to open the created shared_memory_object, the
 "get_bootstamp(std::string &s, bool add = false)" function will return
 "33FABFC2B8FACA010000000000000000", therefore, the client will always
 failed to find the shared memory object.
