I think there is a bug or two in the resource code.

Resource a = new Resource("a name");

ResourceList x = new ResourceList();
ResourceList y = new ResourceList();

x.w(a);
y.r(a);

assertTrue("Read-Write conflict should colide, x.isConflictingWith); // this
will fail

y = new ResourceList();
y.w(a);

assertTrue("Write-Write conflict (when only 1 concurrent writer is permitted)
should colide", x.isConflictingWith); // this will fail

There are others!

I have checked in a JUnit test with some of the failure modes that I think there
are.

I tried some simple quick fixes to the Resource code but could not get it to
work within the time I can spend on it.
