Halts when waiting for a browser to exit after TestLoader Failure

We are using ember exam with the following flags`--split=8 --parallel`. Our CI pipeline was running for multiple hours because the `ember exam` step did not exit.

In the logs we noticed that one of the browsers exited:

```
Test Failure - Exam Partition 7 - TestLoader Failures: : could not be loaded
Died on test #1 at Object.test (webpack://__ember_auto_import__/../../common/temp/node_modules/.pnpm/qunit@2.18.0/node_modules/qunit/qunit/qunit.js?:464:34): Could not find module `` imported from ``
```

However after this exit when the remaining partitions completed, this was logged:

```
.....Out of requested 8 browser(s), 7 browser(s) was launched & completed.
Waiting for remaining browsers to exited.
```

The process does not exit, ever. Regardless of the bug, I couldn't find any flags in the docs that would allow a max wait period to avoid such a situation?
