Milestone:  Boost 1.36.0                          |   Component:  interprocess
  Version:  Boost Development Trunk               |    Severity:  Problem     
 Keywords:  interprocess movable move             |  
--------------------------------------------------+-------------------------
 In the interprocess library, move semantics are provided for all the
 container
 types using boost::interprocess::move().

 The code for move semantics is (mostly) present in the shared object types
 and
 shared_region, but something is missing for it to actually work for these
 classes:
 the necessary specialization of the 'is_movable' trait, and the correct
 signature on the
 copy constructor and assignment operators.

 Attached is a patch that fixes "movability" for several types:
 file_mapping, shared_memory_object, mapped_region, windows_shared_memory,
 managed_head_memory, managed_external_buffer.

 The problem is a little harder for managed_shared_memory,
 managed_mapped_file, and managed_windows_shared_memory, because they
 derive from detail::managed_open_or_create_impl, which currently does not
 have a default constructor.  I chose not to dig into that at this time.
