As subject, a non blocking trylock for the mutex similar to pthread_mutex_trylock.

Why?

I'm working with mutexes everyday and I've never needed this function.

For a piece of performance critical code that continues to execute rather than wait for lock, and then locks later. Do you use something else, or have you never needed to worry about this?

I never needed this, if the piece of code can continue without locking why would it try to do it?

For performance critical code I personnally often use spinlocks.

Anyway, like I always say, SFML is not meant to be a complete threading library, it only provides the most basic things. If you're doing serious threading then you'd better choose a dedicated library.
