The muxes are touching the idle_conns_lock all the time now because they need to be careful that no other thread has stolen their tasklet's context. This patch changes this a little bit by setting the TASK_F_USR1 flag on the tasklet before marking a connection idle, and removing it once it's not idle anymore. Thanks to this we have the guarantee that a tasklet without this flag cannot be present in an idle list and does not need to go through this costly lock. This is especially true for front connections.
