- 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.

Extends https://github.com/astral-sh/uv/pull/13841 — I'll drop that
commit later after that pull request merges but it's small.
I find the split into a "Configuration" section awkward and don't think
it's helping us. Everything moved into the "Concepts" section, except
the "Environment variables" page which definitely belongs in the
reference and the "Installer" page which is fairly niche and seems
better in the reference.
