Re: [boost] [thread] A simply static initializeable mutex

the decrement predicates

bool try_dec() throw() { intword_t local; do { local = m_count.load(mb::naked);

if (! local || local < 1) { return false; }

^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

// use mb::fence to cover *both acquire and release // wrt the result of the decrement } while(! m_count.cas(local, local - 1, mb::fence)); return (local == 1); }

could all look like this: if (local < 1) { return false; } I made a redundant assertion...
