Thanks for the report. With both 5.6 and 7.0 i get with the test script

Execution result: 1.0 sec , string(5) "Hello"
FAILURE
 Expected result:   1 sec , bool(false)

This is correct, as "hello" is flushed before sleep. Please provide additional info on how to reproduce the current behavior you describe. Also, please be sure, there's no any other process listening on the same port.

Thanks.
