And what about your operating system ?

Yes. I understood that the first time through. There was a similiar bug
report already.

Maybe someone else is doing those queries. A library linked to MC most 
likely. I've tried to reproduce that many times and I cannot get neither
the slowdown nor those particualr dns lookups for interface names. I
disconnect the network cable and still I am not able to get the described
behaviour.

Could you build MC with debug symbols and at the time the slowdown occurs 
attach to the MC process with a debugger and get a backtrace ?

Thanks!
