Great.  My sourceforge ID is jtobey, feel free to suggest directory
placement or module naming (I have to familiarize myself with what's
already on the Hurd Sourceforge project).  Currently I have everything
in a /hacks/gnumach/otop/linux/i386 as a psychological aid to avoid
premature portability.

Anything you say.  I would like to build thread-safety into any new
code, though, and I do not intend to support a separate,
single-threaded configuration (for what? speed??).

Btw, I am looking more closely at the OSKit Unix stuff and becoming
more optimistic about it.  Guess I'll have to roll my own mmap()
though, or fish it out of /usr/lib/libc.a .  Theirs just returns
