Thanks for the update. Jonathan, does it make sense to commit the current patch since it solves Paul's problem (and presumably doesn't break existing networking) or should it wait until the "tar cf host:" problem can be solved? I'm basically neutral on which way to go but it sounded like a big network performance issue for Paul when he initially reported the bug. (It might be affecting more people but they probably haven't done the analysis to better understand the problem.)
