No, I didn't think it was a WL specific problem, but something in the
WL environment that helps highlight a problem elsewhere.
Even though the scenario you outline below seems like an edge case,
the 2nd algo does seem cleaner (and more efficient if we are the
coord... don't even try a channel.getState() unnecessarily).
