Yeah, the musl people tend to closely follow the spec, this doesn’t always win them friends: https://news.ycombinator.com/item?id=22682510

Swapping out jemalloc for the system allocator will net you huge performance wins if you link against musl, but you’ll still have issues with multithreading performance due to the slower implementations of necessary helpers.

Sometimes the spec sucks. A lot of the UNIX specs were written before anyone knew how to program multi-threaded systems, and thus are impossible to implement correctly (setenv is probably the most famous example)
