    [trac537] Some explaining comments

commit d1971c14bddf6bcdbc031d1e3195b48ed4bffd62

    [trac537] Use auto_ptr instead of shared_ptr
    
    In some cases, these variables will live only inside one instance and
    will never be copied/shared. Therefore using shared_ptr is unnecessary
    overhead (allocation of the count object, etc).

    [trac537] Put UDPServer variables to nested class
    
    This is to lover the overhead of copying UDPServer - UDPServer is a
    coroutine object and it is copied a lot. This way only single shared
    pointer is copied instead of 10 of them.
