## Summary When installing packages on _very_ slow/overloaded systems it'spossible to trigger bytecode compilation timeouts, which tends to happen in environments such as Qemu (especially without KVM/virtio), but also on systems that are simply overloaded. I've seen this in my Nix builds if I for example am compiling a Linux kernel at the same time as a few other concurrent builds. By making the bytecode compilation timeout adjustable you can work around such issues. I plan to set `UV_COMPILE_BYTECODE_TIMEOUT=0` in the [pyproject.nix builders](https://pyproject-nix.github.io/pyproject.nix/build.html) to make them more reliable. - Related issues * https://github.com/astral-sh/uv/issues/6105 ## Test Plan Only manual testing was applied in this instance. There is no existing automated tests for bytecode compilation timeout afaict.
