I've tested that with ab (the Apache Benchmark): before the change, even with 2 concurrent connections tuntox locked quickly. After the fix, I tested with 10 concurrent connections and it was OK.

Please confirm that the problem is fixed for you, if possible.

@gjedeer I can't connect with latest master - it writes "Rejected friend request from non-whitelisted friend", but I don't specify key "-i" key...

@gjedeer you are right - I can't reproduce this issue anymore.
