beostat_set_last_multicast will set the time that the last multicast event occured. This should not be used unless you really know what you are doing. It is for internal use.
This function relies on the Beostat subsystem, which consists of the proc filesystem on the remote node, the sendstatsdaemon on the remote node, the recvstats daemon on the master node, and two shared memory files in the directory /var/shm. If any part of the system breaks down, this function could fail.
