The problem is that this test has a function with a huge array literal (1 million elements) and executes it only once. This is kind of worst-case behavior for Baseline.
Also, 18 seconds on a very fast Mac, on most machines it will probably be slower.

Don't baseline-compile this function with --baseline-eager as it's very slow in debug builds.
