* Run the garbage collector before creating the big array. It doesn't matter now but if in the future something in node.js core creates a lot of reclaimable garbage, that will break the test's expectation. * The first RSS check was being done too late. The garbage collector might have run before the check, throwing off the 'reclaimed memory' calculation. * Due to changes in how V8 represents the big array internally, the actual memory usage is just below 256 MB on x64. Update the test's expectation.
