> Hi,
> I've found an issue with DefaultExecutor hanging while waiting for PumpStreamHandler to close all subprocess streams if child process was terminated by watchdog (e.g. on timeout).
> I've created a test case for the issue demonstrating working behaviour & issue.
> Test requires commons-io 1.4, Junit 4.x and commons-exec 1.1 to compile
