47 // - allowing "EventManager" to release its event thread immediately, thus not interrupting server execution.
48 // - allowing us to prioritize and control execution of script functions.
49 // Class can use multiple threads for simultaneous execution. Mutexes are used for thread safety.
50 //
51 // 1. Hold an execution queue for scripts
52 // 2. Use threads to process queue, each thread executes one script function on each pass.
53 // 3. Catch any script error and process it
54 //
55 //
56 // Notes:
57 // * Current execution load balancing is optimized for 1 thread, and can cause unfair execute balancing between scripts.
58 // Not noticeable unless server is under high load.
