Yes, this problem should be common for all modes that use the REPL for
fetching information like this. E.g. python-eldoc-function.
Normally, we don't see long-running commands in the user REPL. Or don't
expect the user to switch back to the source buffer and continue
editing. Octave might be a significant exception in that regard.
Anyway, please try the attached combined patch and see if it fixes your
problem.

If you have company-mode installed and enabled, similar problem can
occur (when completion is triggered automatically).
