Hi Xin,
	yes, I am on the cc list. I vaguely understand the complexity of the
issue enough to see its not an easy fix.  In the mean time, I was just
looking for ways to protect the few boxes I have that run proftpd.
Right now running with "rootrevoke on" seems to be the safest, but that
has the side effect of killing active connections.
