Ran on my loaner Alpha, Jack Vogel's SPARC, and is limping on
my loaner PPC.
Since we are talking only kernels here (you *did* say Linux),
a better comparison would be NetBSD... which runs more places
than Linux.

NetScape Commerce Server. 8-).

It still doesn't cover every drive because even the "best around"
can't cover all of the crap hardware out there. IDE/ATAPI is
not a compelling argument; you should just drop it.

I have argued the danger of async writes at length in other
threads. People's inability to accept the implications of
"the completeness theorem" speaks only to their qualifications
as scientists. Anecdotal evidence is not evidence. I would
suggest that anyone believing that async writes are "as safe
as sync writes" needs to take some classes in basic logic
and read a CS text book on finite state automatons followed
by a Mathematics text book on group theory, set theory, and
reversability of set operations.
People who do not understand this are at best, ignorant, and
at worst, Luddites.

Yes. Patches available on request to the author on the
FreeBSD RealTime list.
Does Linux support v10 of the POSIX threading, or only v4 of
1001.3b? This is a serious question.
