I can reproduce this in Emacs 27.1, but `C-g' works fine in Emacs 28 (at

A simple fix is to add a timeout value to the call to =
accept-process-output. For example, adding a 1 second timeout not only =
allows it to recover but also allows Control-g to be honoured. Because =
control-g now is not ignored, the value could be increased =
substantially, say to 10 [seconds].

Whether it's a bug is arguable, and I would argue that that is beside the point. Regardless of whether it is a bug, changing the behavior as I suggested would improve the overall Emacs experience. It should not be a particularly difficult change IIRC from reading the code. Of course, I understand if making this change is not high priority. Additional observation: Setting comint-process-echoes "works" even if the process does not echo (IIRC anyway); Emacs checks that the output doesn't match the input and allows the output to pass unmodified. It's only when the process doesn't echo immediately that causes undesirable behavior. Thus, this also affects the case where the process does echo, but only after a delay. Emacs will freeze while waiting for the echoed output, which is undesirable. Of course, this situation is likely to be rare as a process that echoes generally echoes immediately. > > Recipe to reproduce: > > emacs -Q -f shell > M-: (setq comint-process-echoes t) > sleep 10 > > I'm leaning towards this working as intended.
