Sounds to me like a useful pair of apps would be ChanReserve and
ChanRelease, where ChanReserve operates like ChanIsAvail, but if the
channel is available it atomically reserves it for the calling channel,
until the calling channel either does a Dial, ChanRelease or is hung up.

I don't have time to produce them, but thought I'd toss the idea out in
case anyone feels like picking it up.
