+  - emmit as many as possible through another thread (until the event queue is full?) [1023]
   - see how fast the application can render each frame and measure the necessary time for each _frame_?
   -> determine statistics like, min, max, median, mean, etc.
   -> Or buffered writer to the `std.posix.STDOUT_FILENO`?
   -> I could use this to see if it makes sense to implement a buffered version using a screen buffer (to only render the differences?)
+  - seems pretty good (with some exceptions)
