I know KSE is not related to SMP and will run on UP. my primary
idea is want to run parellel I/O task in same process with pthread,
simply because FreeBSD pthread does not allow me to do multipile
I/O tasks at same time on disk file, of course, it is also conflicted
with SYSV IPC, so I think of KSE. I don't care about SMP, CPU is
enough fast now, I have already seen 1.3G hz CPU, how fast! I think
Intel and AMD can very easy to double their CPU clock, hope I can see
3Ghz CPU in next year. I really do think KSE should work before SMP,
but it is obvious not. think about Apache 2.0, it is already
multi-threaded, FreeBSD pthread will be blocked at disk I/O, it is very
bad for Apache 2.0 .

Best regards,
David Xu
