I think it is impossible to implement this feature.

Two processes, foreground and scan, are running asynchronously. Emacs
does not provide a mechanism to synchronize the two processes. How can
we implement to get the foreground (key-to-command switcher) waiting
for the end of scan? Moreover, we cannot modify the key-to-command
switcher.

Thus, each command called by the key-to-command switcher (e.g. "x")
just sees whether or not the buffer is blocked. If blocked, it
displays a warning message and does nothing.
