* tmbench: Make it more resilient to WSConn breaking
This commit changes the behavior of a broken connection from calling
os.Exit, to instead killing that connection. This also improves
the debug logging, by specifying connection index within errors.
* Rename connStatus to connsBroken
* change logging level
* tmbench: Make sendloop act in one second segments
Previous behaviour was to make the sendloop send all its messages
and then time how long that took. (Possibly waiting if too fast)
This has the same operation when too fast, but stops the loop
after one second. This is useful if a large tx amount is specified
and the ping doesn't get executed. Tmbench no longer crashes on
large rates.
* Update Readme
