// Regression test for http://dartbug.com/7191.

// Starts a sub-process which in turn starts another sub-process and then closes
// its standard output. If handles are incorrectly inherited on Windows, this
// will lead to a situation where the stdout of the first sub-process is never
// closed which will make this test hang.
