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