[Click] Ctrl-C Handling in Click

[Eddie Kohler]

Hi Dimitris,

Are you sure that there isn't a bug in one of your cleanup functions, 
that crashes your router during the cleanup stage?  (Run under GDB or 
something to check.)  I believe that Click will call all cleanup 
functions, in reverse initialization order.  The only reason I'd imagine 
for an early exit is a crash.

Best,
Eddie
