After this change
* comint.el (comint-redirect-results-list-from-process): Fix random
delay.
I am seeing "Blocking call to accept-process-output with quit
inhibited!!" from time to time.
How does this mean? I can't see where comint has inhibited quit.

Might be my fault. Feel free to ignore this.

Just what it says: a call to accept-process-output was done at a time
when quit is inhibited, and the call can block, thus rendering Emacs
completely unresponsive.

quit is inhibited when running timers, process-filters and other
such asynchronous events.
So comint doesn't need to inhibit-quit itself for such a warning to show
up, if its code is executed from a process-filter.
Try to figure out how/when a process-filter (or timer...) can end up
running the while + accept-process-output loop, and then think about
whether that really should happen, and if so make sure the
process-filter (or timer...) uses with-local-quit before running
that loop.

Thanks, this helps.
