This class is the type of mutex to use to protect simultaneous access to the underlying Pool. It is exposed so that users may declare some singleton pools normally (i.e., with synchronization), but some singleton pools without synchronization (by specifying details::pool::null_mutex) for efficiency reasons.
The value of this parameter is passed to the underlying Pool when it is created. See the extensions to the public interface of pool for more information.
The typedef mutex and the static const value next_size publish the values of the template parameters Mutex and NextSize, respectively.
When the Boost multithreading library is completed, the Mutex parameter will be replaced by something from that library providing the same flexibility and will move from an implementation detail into the interface specification.
