+Lazy-mode switch.
+\-L1 (default): Use lazy mode if server supports it, for improved
+performance and decreased latency.
+Some DNS servers, notably the opendns.com network, appear unstable when
+handling lazy mode DNS traffic and will re-order requests. If this occurs,
+you will notice fluctuating response speed in interactive sessions.
+The iodine client will eventually detect this and switch back to legacy
+mode automatically. Use \-L0 to force running in legacy mode

+.B -I interval
+Maximum interval between requests (pings) so that intermediate DNS
+servers will not time out. Default is 4 in lazy mode, which will work
+fine in almost all cases. Decrease if you get SERVFAIL errors in periods
+without tunneled data traffic. To get absolute minimum DNS traffic,
+increase well above 4 until SERVFAIL errors start to occur.
+Maximum useful value is 59, since iodined will close a client's
+connection after 60 seconds of inactivity.
