An event, `m_signal`, is created and signalled when either `m_running` or `m_connected` is changed by another thread, so that the pipe thread knows to interrupt the read. The pipe is now opened as async to allow interruption, and the I/O operations now use overlapped I/O. Other changes include: * Changing `m_pipe` to `HandleT<HANDLETraits>` since `CreateFile` returns `INVALID_HANDLE_VALUE` instead of `NULL` on error. * Remove the call to `WaitNamedPipeA` because it's useless and returns immediately without waiting if the pipe doesn't exist.
