-// using a Windows event.
-// 4. Now the parent can release the write end of the pipe on its side. If
-// this is done before step 3, the object's reference count goes down to
-// 0 and it is destroyed, preventing the child from acquiring it. The
-// parent now has to release it, or read operations on the read end of
-// the pipe will not return when the child terminates.
-// 5. The parent reads child's output through the pipe (outcome code and
-// any possible error messages) from the pipe, and its stderr and then
