Do not merge checkin bae1c688f2 which starts to take the dgp-read-bytes branch into directions apparently unfriendly to stacked channels, which tests for [chan push] on the trunk help us to detect.

A fix was applied that turned out to be more of a band-aid workaround. Now that the real fix is in place, the band-aid is actually preventing it working properly in thie case. Rip it off!

"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.
