the looks of the args in the stack trace, your reactor is (at least partly)
smashed. And, it's trying to recover from a bad handle in the registered handle
set. If that doesn't shed any light on things, try running this under valgrind
to see if it can focus you on the problem area.</FONT></SPAN></DIV>
