---------------------------------+------------------------------------------
 I'm transferring variable number of packed objects (of same datatype)
 using isend/recv.
 ''(I'm new to MPI, so I might be wrong -- but is it true that for multiple
 isends with the same message tag the received message would contain a
 concatenation?)''

 Then I'm reading objects out of the buffer using packed_iarchive. Because
 their number is not known, I need a way to know if I read all objects from
 archive. `packed_iprimitive` already has `position` field.

 Is it worth to make `position()` publicly accessible? The patch against
 trunk is attached.
