Comment(by nickm):

 Looks like this should target 0.2.4.9 unless 0.2.4.8 gets delayed; I'll
 want to test any fix here before shipping it.

 For a fixed-up version of the fix -- I guess we could change the circuit
 ID selection logic so that it doesn't pick any circID currently in use,
 *and* it doesn't pick any circuitID that currently has a queued destroy
 cell.  That would work.

 I agree with the proposition that this isn't the best possible fix.  Not
 sure what the best possible fix here would be; let's get something working
 in place and then go from there.
