Examples of org.jgroups.protocols.pbcast.GMS$Resumer

org.jgroups.protocols.pbcast.GMS
Resumer is a second line of defense: when the ViewHandler is suspended, it will be resumed when the current merge is cancelled, or when the merge completes. However, in a case where this never happens (this shouldn't be the case !), the Resumer will nevertheless resume the ViewHandler. We chose this strategy because ViewHandler is critical: if it is suspended indefinitely, we would not be able to process new JOIN requests ! So, this is for peace of mind, although it most likely will never be used...
