[004] s:error() [004] --- Found that the test in previous was used for testing the the channel get() function timeout and the error occurred on it, but later the checking error changed to: "builtin/socket.lua: attempt to use closed socket" and the test became not correct. Because for now it passes when the socket read function runs before the socket closing, but in this way read call doesn't wait. In the other way on high loaded hosts the close call may occure before read call and in this way read call halts and socket get call returns 'null'. As seen both ways are not correct to check the error. Decided to remove this subtest.
