commit 5e5c7fb50866be4a744642c225205039bb306b88
Author: Oswald Buddenhagen <o...@users.sf.net>
Date: Sun Jun 19 11:19:34 2022 +0200
free IMAP command's payload prior to invoking its completion callback
otherwise the synching may livelock due to failing to schedule follow-up
commands, thinking the buffers are still full. of course, this is
relevant only for commands that failed early and thus didn't free the
payload right after submission already - which will be possible only
after the next commit.
