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).
