Consider using parking lot types

[SuchAFuriousDeath]

The crate https://docs.rs/parking_lot/latest/parking_lot/ claims that it implements faster, smaller and more efficient implementations of
Mutex, RwLock, Condvar and Once than the standard library. Many big Rust crates use it internally.

I'm not a fan of using an alternative to std things unless the difference is huge. The reason is because it cause confusion when reading the code like when encountering RwLock, which implementation is this? std or something else?

We could use type aliases.

The real issue here is does it make huge differences with std?

I saw a speed comparison somewhere, but I can't find it now :D

Also at the top of the readme:
"When tested on x86_64 Linux, parking_lot::Mutex was found to be 1.5x faster than std::sync::Mutex when uncontended, and up to 5x faster when contended from multiple threads. The numbers for RwLock vary depending on the number of reader and writer threads, but are almost always faster than the standard library RwLock, and even up to 50x faster in some cases."

Let's use std version until we have some performance problem then we can try parking_lot.
