But arn't there new types of mutexes and new hi resolution timers? I guess I'll just dig and see what I find and report back.
Has any one done pthreads on the gumstix? I imagine some one has ....but if I find out any thing that should be mentioned I'll try to wiki it. Thanks for the awesome suport!

So, as far as I know there is no API for the kernel preemption stuff.
It's either enabled or not.

This is different than the RTAI or RTLinux.

As far as poix threads go, there's an O'Reilly book on using posix
threads. Most of the information should be available online as well.
