Comlib multicast strategies failed to completely initialize the CkSectionInfo
cookie for multicast msgs that were going to already used array sections. The
first message to a 'new' section traverses a different path through comlib code
and hence did not suffer the same fate. The second message, however, ended up on
remote PEs with an not-completely-initialized cookie, causing section hash object
lookup to fail. This crashed the program.
