Comment (by kevin8t8):
I've been tracing things through, but haven't found the cause yet.
Just for any other devs, the cmd_parse_fetch() for the flag changes is
calling imap_set_flags(). This then triggers mutt_set_header_color() ->
mutt_pattern_exec() -> MUTT_HEADER: -> msg_search() ->
imap_fetch_message(). So that's why we see the BODY.PEEK being sent in
a7164 before a7163 is even finished.
When processing a7164, it marks a7163 done, so by the time it gets back to
the outer imap_cmd_step(), all the idata->cmds are already done. So the
last "IMAP queue drained" we see in the log occurs then.
At first I thought it was the nested imap call leaving something goofy,
but I couldn't see any problems (yet).
So the question is where is it hanging? After the mx_check_mailbox(),
check should be MUTT_FLAGS so it should be calling update_index(). After
update_index(), it outputs a message that would be logged, so my best
guess is in update_index().
Dave, I'll create a patch file with some more debug statements, just so I
can confirm or deny where it's freezing. I would appreciate if you could
apply it and try to recreate the freeze.
