	The following script contains MT modes for various plugins, save it as <tt>mtmodes.avsi</tt> and place in your auto-load folder. The script is a work-in-progess, there's still lots of plugins that need to be tested and validated. When the script is finalized, the only thing the user will have to write in his script is the <code>Prefetch</code> call, all <code>SetFilterMtMode</code> calls will be hidden in a single <tt>.avsi</tt> script.

			Note for filter writers: filters can report their mt modes in their SetCacheHint, in this case the manual setting is not necessary.

	The other difference is how you actually enable multithreading. Calling SetFilterMTMode() is not enough, it sets the MT mode, but the MT mode only has an effect if MT is enabled at all. Note this means you can safely include/import/autoload your SetFilterMTMode() calls in even single-threaded scripts, and they will not be messed up. Uhm, onto the point: You enable MT by placing a single call to Prefetch(X) at the '''end''' of your script ~~(but '''before''' a return statement)~~, where X is the number of threads to use.
