Hi
I would like to put forward an implementation of a lightweight mutex for MacOS. I have tested it with shared_ptr_mt_test.cpp without problem.
You don't have proper memory barriers for MP-safety. Abusing the scheduler is also not good.
Do you have any specific suggestions which would make this design at least as good as that in lwm_gcc.hpp?
http://www.boost.org/boost/detail/lwm_gcc.hpp is also broken. Do you have "futexes" on Mac? If so, you might want to take a look at http://listman.redhat.com/archives/phil-list/2003-October/msg00029.html http://listman.redhat.com/archives/phil-list/2003-October/msg00030.html And, perhaps, also http://groups.google.com/groups?selm=3FA61F96.223FDE85%40web.de regards, alexander.
