I'm still trying to get a correct mental model of how all this is working. I assume that, if I gather the threads using: (mapc #'thread-join threads) None of the threads ever become the "current thread", and so C-g would only ever signal quit to the main thread. So maybe instead of mapc, we do: (dolist (t threads) (condition-case nil (thread-join t) (quit (thread-signal t 'quit)))) According to my (limited, untested) understanding, that ought to do the right thing. While we're here, one more quick question. Gnus's IMAP servers collect output by running this on a loop, until there's no more output: (accept-process-output (truncate nntp-read-timeout)) nntp-read-timeout is 0.1, and truncate turns that into 0. Is (accept-process-output 0) the same as (accept-process-output nil)? Thanks, Eric
