* Stop the segfault in iogt-2.4. First by changing the UpdateInterest()dgp2014-05-011-1/+8
| | | | | | | call that triggers it. "downChanPtr" may no longer be the right argument at that point. Second, after ending the segfault, the test became an infinite loop (nested unstacking?! whoa.), so revised the test to one that terminates (and passes). Left behind a comment that the recursive unstacking case may require more examination.
