Fio will normally verify IO inline from the submitting thread. This option

-are of the form 'type:hostname or IP:port'. 'type' is either 'ip' for
-TCP/IP, or 'sock' for a local unix domain socket. 'hostname' is either
-a hostname or IP address, and 'port' is the port to listen to (only valid
-for TCP/IP, not a local socket). Some examples:
