Expanding on the improvement in JAVA-318, it might be useful to allow pools to be explicitly named for the purposes of identifying a specific pool via JMX. For example, if I have two applications in tomcat that connect to the same server with the same options, I currently can see both pools with version 2.5.3, but I don't know which belongs to which application.

It looks like the easiest way to allow an application to label pools would be to add a name field to MongoOptions. This could then be added to the ObjectName generated in DBPortPool.Holder, if a value has been supplied by the application. The hashcode portion of the ObjectName added in 2.5.3 would probably remain regardless of whether the application supplies a name, since there's no guarantee that multiple applications would not inadvertently provide the same name.
