关于thread和actor下面这段话讲的很好
Experienced developers have learned to be very careful with unrestricted threads and various blocking mechanisms of a (real-time) operating system, because they often lead to programs that are unsafe and difficult to reason about. Instead, experts apply the following best practices of concurrent programming:1.Keep data isolated and bound to threads. Threads should hide (encapsulate) their private data and other resources, and not share them with the rest of the system.2.Communicate among threads asynchronously via messages (event objects). Using asynchronous events keeps the threads running truly independently, without blocking on each other.3.Threads should spend their lifetime responding to incoming events, so their mainline should consist of an event-loop that handles events one at a time (to completion), thus avoiding any concurrency hazards within a thread itself.While these practices can be applied manually on top of the "free threading" approach, a better way is to use the Active Object (Actor) pattern, which inherently supports and automatically enforces the best practices of concurrent programming.
