  So, I decided on three locking strategies:

  No-Lock
  Optimistic locking
  Pessimistic locking

  As a default, the no-lock behavior does exactly what the name implies. Nothing. This is the default because my research shows that for 99% all of this is not an issue and every interaction at this level will slow down the whole application.

Aren't the mutexes in the more modern implementations (like Cosmo [0]) & runtimes (like Go [1]) already optimized so applications can use mutexes fearlessly?
