1213129 - Share the code we use to get worker counts for the test suites

Status: RESOLVED FIXED

(Core :: JavaScript: GC, defect)

Description

[Terrence Cole [:terrence]]

Attachment: share_worker_count_code-v0.diff

The jstests suite has a simple get_worker_count routine that checks a few reliable places for core counts.

The lib/jittests.py script, on the other hand, sets HAVE_MULTIPROCESSING to True when it does the import, which includes adding cpu_count to the lib/jittests.py namespace. This is imported first by jit_tests.py, which does the above. Later (relatively), when jit_tests.py sets up the argument processor, it checks jittests.HAVE_MULTIPROCESSING before calling jittests.get_cpucount. Because we wouldn't want to be crazy and re-used the loader's cached copy? Who knows!

I've chosen to standardize on the first of these methods.
