To reproduce the slowdown, those condition should met:

- Some nameserver exists in /etc/resolv.conf
- A default route exists
- The nameserver(s) do not respond and the error
  is not immediate ("connection refused" or "no route to
  host" are immediate errors, so no timeout to wait).

Can you please give me the option to include debug symbols and 
the command line to attach MC with the debugger?

Thank you again.
