I noticed that problem once as well, but it was while issuing the "rm *" command
on the shared space from cssh to 5 machines at once, which seems more
understandable that you'd see a problem doing it that way.  However, it should
be able to handle that and I haven't been able to reproduce it yet, so I
couldn't track down what actually caused it.  I can send you my config details
if you'd like to compare.
