7 tests fail on i586 architacture

[MeggyCal]

Hi, thank you for this tool! Anyway, I was trying to package it for openSUSE and ran into error on i586 architecture (32 bit), other (64 bit) architectures are fine. The main theme looks like:

[   21s] >       sys.setswitchinterval(original_switch)
[   21s] E       ValueError: switch interval must be strictly positive
[   21s]

[   21s] ************************** pytest-run-parallel report **************************
[   21s] 3 tests were not run in parallel because of use of thread-unsafe functionality, to list the tests that were skipped, re-run while setting PYTEST_RUN_PARALLEL_VERBOSE=1 in your shell environment

[   21s] PARALLEL FAILED test_thread_unsafe_function_attr.py::test_should_not_be_marked

Could you please take a look into it? The full pytest failure log is in the attachment (too long to paste here).

Odd. We get orig_interval from sys.getswitchinterval. Not sure how it ends up not positive. Let me see if I can reproduce in a 32 bit Linux docker container.

I can reproduce this inside a 32 bit linux docker container.

@MeggyCal I opened #54

Hi, I confirm #54 fixes the issue for me. Thanks a lot!
