What are you talking about?
I've never seen that. Many years and many machines.
You've got something weird misconfigured somewhere like a plugin trying to do a failing dns lookup or something.
However I have seen mystery hangs in general, which can happen to almost anything.
I had a machine one time where a self-built version of midnight commander would always hang for several seconds on startup. Never saw that before or since. You can not say "mc takes something like 5-10 seconds to start up" even though it did on that machine that time.
I don't remember the details, but it turned out to be some combination of environment/context ie a particular terminal on a particular client sshing to a particular server where mc itself was, env variables, and/or setting in a mc config file. Might have been something to do with locale or TERM, or.. . I really have no idea anymore.
But the hang was fixed by hunting down the config problem, and I've never seen it before that, nor since.
