Spawning async methods – Am I doing it right?

What's also astonishing is that some locks are not thread-safe (as in being !Send ) That was pretty unexpected for me as you intuitively think that thread-safety is inherent to locks.

I think this is due to restrictions in some OS's API that you have to unlock a mutex from the same thread as you lock it from. This makes the lock guard of a mutex unable to be sent between threads.
