fix sigabrt in parfors tests
This fixes a test, where a non-thread safe container is written to
during testing

To reproduce on at least `linux-64` and `osx-arm64` (and probably
others):

```
NUMBA_THREADING_LAYER=workqueue SUBPROC_TEST=1 ./runtests.py -m 32 numba.tests.test_parfors.TestPrangeSpecific.test_tuple_hoisting
```

On `linux-64`, this can be debugged with `gdb`:

```

On `osx-arm64` we can use `lldb`:

```
