Synchronization problem under OpenMPI 1.6.5 #37

This is a reminder to further investigate a problem discovered in issue #35.

With a linear chain of applications, there seems to be a synchronization problem when MUSIC is compiled with OpenMPI 1.6.5. With the standard configuration, p2p communication does not properly synchronize with the receiver such that expected semantics for maxBuffered=1 is broken.

A workaround is to configure MUSIC with --disable-isend.
