commit 485f783f882ed026cdbfede89aa7bddad3fffdf3 Author: Eric van Gyzen <[email protected]> AuthorDate: 2023-04-14 21:11:29 +0000 Commit: Eric van Gyzen <[email protected]> CommitDate: 2023-04-14 21:16:05 +0000 limits_test: validate CPU time used, not real time RLIMIT_CPU applies to CPU time, not real (wall-clock) time. This test failed in AWS, where the real time was 5-7 seconds. Sum the user and system CPU time used, and validate that. While I'm here, don't bother specifying -s exit:0 or -e empty, since those are checked by default.
