Recursive make and the pitfalls of -j parallel builds

Original: Recursive `make` and `-j`

A technical blog post by Arthur O'Dwyer examines how recursive invocations of GNU make interact with the -j parallel jobs flag, a long-standing source of subtle build-system bugs. Developers are discussing why parallel jobs can misbehave when a makefile recursively calls make, and what workarounds exist. The piece has drawn attention from programmers interested in build tooling.

Why now: Build reproducibility and parallelism quirks in GNU make are a recurring practical pain point for developers
