This commit removes the simple/test-event-emitter-memory-leak test for being unreliable with the new garbage collector: the memory pressure exerted by the test case is too low for the garbage collector to kick in. It can be made to work again by limiting the heap size with the --max_old_space_size=x flag but that won't be very reliable across platforms and architectures.
