FreeBSD 8.0

kse 是 FreeBSD 支持 M:N 线程模型的库，不过因为太复杂，已经被去掉了。

http://www.sunchangming.com/blog/?p=2660

http://docs.freebsd.org/cgi/getmsg.cgi?fetch=501996+0+/usr/local/www/db/text/2008/freebsd-current/20080316.freebsd-current

貌似 FreeBSD 还是坚持得比较久的，Solaris, NetBSD 早就放弃了 M:N 模型。目前主流的实现都变成 1:1 模型了。

http://en.wikipedia.org/wiki/Thread_(computer_science)

libkse, src/lib/libkse, 废弃

libc_r, src/lib/libc_r, 废弃

libthr, src/lib/libthr

$ ls -l /usr/lib/libpthread*

lrwxr-xr-x 1 root wheel 8 11 21 22:54 /usr/lib/libpthread.a -> libthr.a

lrwxr-xr-x 1 root wheel 9 11 21 22:54 /usr/lib/libpthread.so -> libthr.so

lrwxr-xr-x 1 root wheel 10 11 21 22:54 /usr/lib/libpthread_p.a -> libthr_p.a

可以看出 libpthread 默认都链接到 libthr。但有个奇怪的问题，就是

gcc -pthread 和 gcc -lthr 得到的 gprof 结果，居然不一样。

而且在 thread func 里面做的事情，居然也 gprof 不到。不知道是不是我自己系统的问题。

一些想法得到验证 :-)
