Quick question for you...

I am trying to port an application on NetBSD using intensively posix 
threads.
I had a lot of issues in the past with NetBSD about this.
I just heard about NetBSD 2.0 and its new changes! Do you have any 
roadmap about the final version of the kernel?
How can I test it and use current development version of this system?

Thank you very much in advance.
Eric.
