The command:

./pants tailor --check update-build-files --check

16:16:04.04 [INFO] Starting: Building black.pex from black_default_lockfile.txt

it should definitely not take that long..does

top

show that things are happening?

does it improve running one goal at a time?

it shouldn't matter - goals run sequentially with Pants currently. I suspect that's a red herring and for some reason building the Black PEX was hung

-ldebug

will have a lot more info
