Subject: [Boost-users] [threads] calling unlock twice

I wrote a code which used a RAII idiom to lock multiple mutex instances in
ctor and unlock them in dtor.
This resulted in the class similar to:
lock_many(mutex& m1, mutex& m2, ...)
: m1_(m1), ...
boost::lock(*m1_, *m2_, ...);
//some asserts here, which ensure that either all mutex pointers are
NULL or unequl to each other
if(m1_==NULL && m2_==NULL && ...)
return; // all are NULL no unlock needed
