There are reports of multi-hour runs (see JDK-8271613). We can parallelize the test configurations for this test to make it hurt less. Also, timeouts need to be increased for `TestUpcall` test configs, because some of them are very slow in fastdebug mode.

How is this test executed? I think when this was added the idea was that this had to be an advanced test which had to be run explicitly by users, but would not be picked up in the various test groups/tiers. I'm defo not seeing it running in the `jdk_foreign` group, so it shouldn't run on tier4. I'm not sure what's happening?
