Issue on macOS 10.15.6/Python 3.8.5 #10

Open d3v1an7 opened 4 years ago

I've been unable to get this running using Python 3.8.5. Was trying to run the example in the README without success, so tried running the test suite instead:

================================================= test session starts ==================================================

capturer/tests.py::CapturerTestCase::test_combined_capture_same_process

It essentially freezes on test_combined_capture_same_process "forever". After double keyboard interrupt:

A final third keyboard interrupt shows 3 tracebacks, all for keyboard interrupt (let me know if you'd like these as well).

I really thought it was just me (am new to Python!), but decided to run against 2.7.x (as close as I could get to what is running in Travis) and voila!

Let me know if you need any other info. Excited to get this working to replace my extremely sketchy asyncio workaround 😂

I get the same problem on macOS 10.14 with python3.8. The tests work with python3.7 on the same host.
