Hi! After following the instructions for building from source I got some test failures when running cargo tests --workspace:

Running with RUST_BACKTRACE=1 showed a bunch of Os { code: 24, kind: Uncategorized, message: "Too many open files" } errors. In my shell ulimit -n is apparently 256, so I tried doing ulimit -n 1000 and that fixed things. Would it make sense to add a note about this to the build instructions? (Or maybe my open files limit is unexpectedly low?)
