Still because of commit id 'fe8f1c8b' where we generate a REF for the Register and that's transparent to the consumer (e.g. how would they know they need to ensure that Deregister is called), thus the purpose of this patch is to find a way to Deregister if it's determined that the consumer hasn't by the time of the "last" REF we'd have. This solution to this problem is to alter the processing to have the remoteClientCloseFunc handle performing the Deregister calls instead of the remoteClientFreeFunc because there's no way FreeFunc would be called unless the Deregister was already called.
Oh, this would explain the missing bit that I was probably missing. This patch looks like what I really wanted this to be handled as, but still, would you be able to sketch out a reproducer for the unlucky ones, like me? Thanks a lot.
