   Wait until the number of TCP TIME_WAIT connections drops below 100.

   Kills :doc:`nginx <modules/nginx>`, then polls netstat and cleans up lingering TIME_WAIT connections
   by writing to /proc/net/tcpdropsock. Emits the event SERVER_CLEAN when the
   number of TIME_WAIT connections is under 100.

   Use waitfor=SERVER_CLEAN in your script sections to delay execution until
   the server is clean between test runs.

   Variables:
     WAIT_GREP - IP prefix to filter connections for cleanup (default: 10.221)

   Usage:
     %import@server waitcon WAIT_GREP=10.100
