i know - therefore my question concerning while-no-input!
In fact: ECB has some tasks which should be run really(!) stealthy, like
checking if a dir is empty, getting the VC-state of all files in a dir,
checking which files in a dir are read-only... in case of a remote host
an iteration of such a task (i.e. for one file of a dir) can be potentially
long lasting...

With the current available elisp-tools (macos, functions etc.) ECB can run
these tasks only pseudo-stealthy...therefore a way to make this really stealthy
would be very important for ECB so users are not blocked...

I have no preference how to achieve this (while-no-input, with-local-quit etc..),
but i would be great if i could achieve this goal at all!

see above - what would be the best way to enable real stealthiness?

Thanks a lot,
