I'm thinking of adding system load stats to the status servlet. What do other's think about it? It would use JNI to call a native lib and it would only work on unix, but it would be good to have.
Well, I'm working over a year now on a project that I've called apr-java. This is a thin (for now) wrapper around apr and apr-utils, so it will be supported on all platforms the apr is. Things like true shared memory, process mutexes, advanced networking, pipes, etc. that are missing from the core Java will be supported. Usages are many, like writing high-performance networking connector for Tomcat, making Tomcat a Apache mpm-like server with multiple JVMs, etc...
I hope I'll have a working start point this month, so we could discuss is it worth the effort at all, would it fit inside JTC, commons, or to go trough apache incubation as a separate project.

Anything that allows Java to do things only native apps can do instead of beeing as dumb as the dumbest platform is worth the effort :-)
JTC already has some apr and jni code ( it is true, using the dead jk2 model ), why not start there and if it grows big enough move to commons?
BTW - it would be really great if it would use the SWT model, i.e. JNI methods matching exactly the APR signatures and param types, with minimal ammount of C wrapper code. It works really well, and it's the easiest to maintain and fastest of all JNI flavors I've seen.
