OK, I'll fix mine if you fix yours in ckpt.c, clm.c tlist.c, and
util.c :-)

Yes, I fixed that a long time ago. The library coordinates the opening
of the channel with the exec side. The exec side sends an open mcast
which everyone receives so that all nodes have a notion of how many
opens there are for a given channel.  When the originator processes the
open mcast it also completes the open operation by sending the status to
the library instance that made the request.
