Sets up three requests to a resource that will take 0.6 seconds to load:
1) timeout first set to TIME_NORMAL_LOAD, after TIME_REGULAR_TIMEOUT timeout is set to 0, asserts load fires
2) timeout first set to TIME_NORMAL_LOAD, after TIME_DELAY timeout is set to TIME_REGULAR_TIMEOUT, asserts load fires (race condition..?!?)
3) timeout first set to 0, after TIME_REGULAR_TIMEOUT it is set to TIME_REGULAR_TIMEOUT * 10, asserts load fires
