For my part, I'm of the opinion that threads support based on the native
thread libraries is the way to go. I say based on, because it's unlikely
that the native threads libraries will work with glibc without at least
some porting. However, I do believe it would certainly be better to go
that route than to use the linuxthreads port.
In FreeBSD's case, the native thread support is very much under
development right now. FreeBSD 5.x has three native thread libraries,
not counting the port of linuxthreads, which also runs with the native
libc.
IMHO, the glibc port to FreeBSD is really only about half done. And it
was the easy half. There are still issues, and thread support is one
of them. Either someone will work on them, or not. If not, I can always
restart the native libc port...
