## Summary This PR fixes a subtle bug in `pip install` when using `--reinstall`. If a package depends on a build system directly (e.g., `waitress` depends on `setuptools`), and then you have other packages that also need the build system to build a source distribution, right now, we don't share the `OnceMap` between those cases. This lifts the `InFlight` tracking up a level, so that it's initialized once per command, then shared everywhere. ## Test Plan I'm having trouble coming up with an identical test-case and hesitant to add this slow test to the suite... But if you run `pip install --reinstall` with: ``` waitress @ git+https://github.com/zanieb/waitress devpi-server @ git+https://github.com/zanieb/devpi#subdirectory=server ``` It fails consistently on `main` and passes here.
