Uno/Term/Thread Safe

Thread Safe

Code is Thread Safe, if it can safely be called concurrently by multiple threads. This typically means, that it protects critical sections by locks. Thread Safe code is thread aware.

In UNO, components need to be declared Thread Safe, if doing blocking I/O, so that the components system calls can be interrupted. Thread safe components may also be used to allow high concurrency, while avoiding the runtime overhead of external locking.
