Hello Yeqing,

You might want to write to "hackers at" ...
... some of those guys *wrote* these syscalls.  However,
since it's a question, I'll take a stab at it.

Have you read:

$man kse
$man 3 mac
$man libthr  ?

Also, see

However, I think that KSE was used in 5.x and 6.x
and then dropped in favor of a 1:1 threading model
when 7.0 was released (I'm sure some "hacker@" can
correct this information if I'm wrong).

I hope this is helpful to you.
