`mode-line-format' contains per default `mode-line-remote', introduced
a couple of weeks ago. Evaluating this variable calls `file-remote-p'.
I guess this is the reason of the observed behaviour.

As you said, it shouldn't be a performance bottleneck, because
`file-remote-p' doesn't connect a remote machine ever.

As far as I see in the code, `expand-file-name' doesn't call
`file-remote-p'.

Best regards, Michael.
