This one used to rely on a few spin locks around lists manipulations only but 1) there were still a few races (e.g. when aborting, or between STAT_ST_INIT and STAT_ST_LIST), and 2) after last commit which dumps htx info it became obvious that dereferencing the buffer contents is not safe at all. This patch uses the thread isolation from the rendez-vous point instead, to guarantee that nothing moves during the dump. It may make the dump a bit slower but it will be 100% safe. This fix must be backported to 1.9, and possibly to 1.8 which likely suffers from the short races above, eventhough they're extremely hard to trigger.
