Pants

Is everything in `~/.cache/pants` keyed off of the OS/arch?  Or more concretely, if I'm on a macbook, can I bindmount `~/.cache/pants` into a Linux container and run `pants` from both within and without the container?  (I don't have a macbook so I'm in part thinking out loud here.)

Seeing `pex_root/venvs/` I admit I'm skeptical

Yeah, I would recommend inspecting that closely

If the PEX file is _not_ multiplatform, you're good to go. If it is, then, assuming your not using something like `PEX_PYTHON=python3.10 my.pex ...` to run the PEX, you should be good to go as long as the Pythons used on the Mac and Linux side don't have the same absolute path for the Python executable: <https://github.com/pantsbuild/pex/blob/5c0c29c192bd99335b5a1ab5b68a0f8556cd97aa/pex/variables.py#L773-L900|https://github.com/pantsbuild/pex/blob/5c0c29c192bd99335b5a1ab5b68a0f8556cd97aa/pex/variables.py#L773-L900>. I did not think to defend against that corner case.

I'd be happy for a Pex issue though that asked for explicit support for multiplatform support in 1 Pex cache to make sure docker-style uses of shared cache do the right thing. Better to be planned than sort of work by accident.
