- Various "FD" to "Handle" - Existing Multiprocess implementation moves to _posix. - Stub implementation for _win. At the moment, multiprocess_exec_win.cc contains implementations of both Multiprocess methods and MultiprocessExec functions. This will need more work in the future, but reflects the idea that all tests should be in terms of MultiprocessExec eventually. Currently, this works sufficiently to have util_test succeed (including multiprocess_exec_test, and the recently ported HTTPTransport tests.)
