    Execute code block while bounding its execution time between min and max. within blocks may be nested. All methods in this trait which take maximum wait times are available in a version which implicitly uses the remaining time governed by the innermost enclosing within block.

    Note that the timeout is scaled using Duration.dilated, which uses the configuration entry "akka.test.timefactor", while the min Duration is not.
