There is a bug but I am unable to pin-point where. All I could narrow it down to is that smtpmail open-network-stream hangs when it is invoked from within accept-process-output with timeout of 1 secs of url-retrieve.

I found a workaround for my needs by using smtpmail-queue-mail.

That's not my experience, really – url-queue.el is based around firing off `url-retrieve' from timers, and I've never seen any problems.

Sheer luck, IMO. I don't really understand the need to run subprocesses from timers, since subprocess support already includes async operation and built-in time-outs.

This is a fairly common configuration. Consider a minimal IDE setup: 1. Code completion popup which is shown when Emacs is idle for XX ms. 2. Eldoc hints which are shown at YY ms after the user stops typing. When both are implemented using HTTP calls, you get "timers with subprocesses". In fact, I have a configuration like that (based on url.el) and get an occasional strong freeze (one that requires 3 C-g's to get out of) about once every 1-2 weeks. Haven't found a solid repro so far, so if the reporter has something stable-ish, I'll be following this report intently.

I wonder why others are not able to reproduce the bug too (my system is debian/bullseye)- for now I am using the following workaorund to avoid emacs hang. 

(defun rn-adv-wto (fn &rest args)
  (with-timeout (13 (signal 'error (format "adv-wto: %s" args)))
    (apply fn args)))
(advice-add 'accept-process-output :around #'rn-adv-wto)
