Subject: [boost] [mpi] all_reduce and MPI_IN_PLACE like feature

MPI_Allreduce offers the possibility to use the same buffer
for the send and recv data:
It seems that boost's all_reduce does not allow such a feature.
First, I would like to know if the previous statement is correct and, if
yes, if it was just overlooked or if there was a reason for that?
Just in case, I filed a ticket regarding that issue, along with a
tentative patch, in https://svn.boost.org/trac/boost/ticket/6704
