Mac OS X since 10.6 also offers libdispatch where the kernel itself can help processes decide when to create new threads. The project is opensource and it looks like it might be adopted by FreeBSD too.

<http://libdispatch.macosforge.org/>

The API is very nice to use with blocks (Apple extension to C). Here is a multithreaded foreach creating tasks executed by libdispatch:

	dispatch_apply(count, queue, ^(size_t i) {
	   printf("%u\n",i);
	});

Can we do something like this in D, given all the sharing protections?
