+When sending a SIGHUP to a vtun client process which is unable to connect
+to the remote server, it will attempt to reconnect without sleeping between
+consecutive attempts. This results in a CPU usage spike, and a flood of
+data sent to syslog.
+This patch causes the first sleep after SIGHUP to be discarded, then allows
+sleep to be used again in subsequent iterations.
