+Disable libasyncns usage in Gajim
+
+libasyncs creates several threads and lets them all block in recv() on a unix
+socket. Due to a kernel bug (RHBZ#529202) they go into uninterruptible sleep
+for a long time, causing inflated loadavg measurements and scary warnings from
+the hung task watchdog in dmesg.
+
+Thankfully libasyncns is not essential for Gajim to work.
