Process with id 3112563 is holding a write lock.
A stack trace from this process tells us that it is busy building something.

Steps To Reproduce

Start multiple builds of firefox from staging on the same machine
The second and following processes get stuck evaluating

Expected behavior

First process should drop the write lock as soon as it's done evaluating

nix --version output

nix (Lix, like Nix) 2.92.0-dev-pre20241211-92ed9fe
