[mpich-discuss] //Ssend(...) safe?

Hmm, mpi21-report.pdf - S.41 

"... Ready send can be implemented as a standard send. In this case there will be no
performance advantage (or disadvantage) for the use of ready send. ..."

In my eyes that means that the implementation can use "ready send" for "standard send", can't it?
