  • Fix jit_allocator locking race condition (when PPU thread is faster than compilation threads). Thanks for @Megamouse for pointing out this bug, also added a minor optimization here for eliminating locking when not needed.
  • Fix weakness in concurrency for jit_module_manager lock management, allowing better execution for CPUs with more than 20 threads.
