Ach.  I don't know why, Freddy; I thought you had seen it.  Alex is fixing
a real problem, which he tested.  I suppose if our unit tests were more
rigorous, they would have exposed the state problem you refer to.  

What to do?  It seems we need to read the extended error data AND leave
the stream in IDLE state.  If we come up with a way to do that fairly
soon, we can apply it to the 0.62 branch as well as the trunk.  At some
future point -- depending on how critical this is (not clear, to me) -- we
can release 0.62.1, with or without other fixes.
