Right, but he's already porting it (whatever it is) from Linux to DOS, so I assume he has some urge (need? want?) to do some things himself. At least with DR-DOS (or RDOS or similar), it's less "impossible" than standard MS-DOS or FreeDOS. BTW, it seems GNU pth 2.07 just uses an "auto-sizing ring buffer" for its fake pipe, esp. for 2.03p2. And it has a configure option to disable pipes altogether (and thus disables threaded signaling but that allegedly speeds up threads 10x overall).
