nsync

A separate question -- is using the upstream nsync as safe as using your fork?

It appears most of the improvements by Justine are upstreamed into nsync itself which doesn't have any of the baggage of cosmopolitan.

I got to sit behind the board when a friend of mine ran sound for nsync.

I see a stream of improvements to the vendored in nsync inside the cosmopolitan project [1].

Aren't most of these nsync tricks also implemented in glibc mutexes?

Perhaps nsync or Cosmopolitan would have made my code much faster.

I was amused to find this consistent across BSB, NSync and Britney Spears (and I didn't like very many of her songs).

If your program links pthread_create() then cosmo creates a dlmalloc arena for each core on your computer and uses sched_getcpu() to index them combined with raw nsync locks.

The core of this a library called nsync.

Being able to exploit those two features resulted in a considerable improvement in nsync's mu_test.c benchmark for the contended mutex case, which I measured on RPI5.

All I remember is from watching The News Hour about Bill Clinton having sex and bombing places and reading about nsync on the back of juice boxes.

I've gotten a lot better with them now, and while I still personally will gravitate towards messaging-based concurrency over locks, I do feel the need to start playing with some of the more efficient locking tools in C, like nsync (mentioned in this article).

Remember those "Text 53646 to this number to get your NSync ringtone!!!" ads that used to blanket the airwaves?

I paid $10/month for all nsync!" I love what CM is doing, but if lay persons and even "experts" are getting burnt, who is responsible?

Maybe I look at "nsync", see its mutex (may) change the fairness semantics, and then decide not to adopt it because this may break my callers; or its enough that it may change the fairness semantics, and I don't have the budget to test nsync or a new implementation based on the nsync algorithm to determine if the semantics differ.

In your argument you seem to throw everything in but the kids Nsync, and even though you are having a feel day with this I am here to bring you back into reality.
