1101	[MPI] Const-incorrectness in boost::mpi::status	daniel_kruegler	Douglas Gregor	"There are two member functions in class boost::mpi::status which lack const qualifications although they are immutable:

(a) bool cancelled(): The documentation says:
""Determine whether the communication associated with this object has been 
successfully cancelled.""
The implementation delegates to MPI_Test_cancelled, which according to
the internet documentation does use it's MPI_Status* argument is IN parameter.

(b) template<typename T> optional<int> count():
Here also the docs don't imply a mutable operation. The implementation delegates
(under some circumstances) to MPI_Get_count, which also does not modify MPI_Status
from a user perspective. The same function *caches* the result in the data member
m_count, but this is the classic example where this member should be declared
mutable therefore.
