Garbage has been collected

I've managed to successfully run a garbage collection cycle without causing a crash:

def testCollect {

  // Allocate a string that's not a constant.

  var sampleString = String.format("a{0}", "b");

  // Force a collection

  tart.gc.GC.collect();

  // Ensure that the string is still valid.

  assertEq("ab", sampleString);

}

Woot.
