According to the documentation and tests, a negative value for the “workers” parameter to compileall.compile_dir() should trigger ValueError. But if Python is built with “configure --without-threads”, the parameter is not checked. So I propose a patch to fix the implementation.

FAIL: test_compile_workers_non_positive (test.test_compileall.CompileallTests)
Traceback (most recent call last):
  File "/home/proj/python/cpython/Lib/test/", line 172, in test_compile_workers_non_positive
    compileall.compile_dir(, workers=-1)
AssertionError: ValueError not raised
