I need to hide boost locks from the rest of my code. I have a factory 
class that creates locks ( we have ACE and Boost locks implemented).
to create the locks, in boost, we use the new keyword and to unlock ( 
release the lock ) we delete the locks. The mutex object using which the 
locks are created are shared among the threads .

// create lock
//my_mutex is a mutex factory object with b_mutex as a public member of 
type Boost::mutex
boost::mutex::scoped_lock* lk = new boost::mutex::scoped_lock( 
my_mutex->b_mutex );

// deletion of  lock
delete lk;

is this a correct way to do this ??
