           Summary: Implement waitTimeout() in std.process
           Product: D
           Version: D2
          Hardware: x86
                OS: All
            Status: NEW
          Severity: enhancement
          Priority: P1

Currently wait() is blocking, while tryWait() would have to be used in a loop
in order to simulate waiting until a timeout is reached. It would be great if
waitTimeout(Pid, Duration) was provided as an API.
