This code is present in all the original interpreters using Digital iMUSE, and it was implemented in order to allow slower CD drives to fetch new data without having music skipping during load times. This works by basically flooding the music buffer with data whenever a big resource, a voice file, or a SMUSH movie is loaded. Arguably this is not needed for devices using SSD drives, but since this change had its benefits on a quite old laptop of mine, and since the memory overhead is very minimal, I have decided to implement it.
