D2 changes! Removed druntime from the repository again.. Sorry :/ Updated the druntime port a bit, now requires druntime from trunk. Added info in runtime/README on how to get druntime from trunk. Added patch to add LDC support to druntime. Removed some debug logging from D2 builds. Fixed broken typeinfo for const/invariant in D2.

private import tango.core.Thread;

extern(C) void printf(char*, ...);

void foo()
{
		printf("-- I am here\n");
		Fiber.yield();
		printf("-- Now I am here\n");
}

void main()
{
	Fiber f = new Fiber(&foo);

	printf("Running f once\n");
	f.call();
	printf("Running f again\n");
	f.call();
}
