I wasn't planning to trigger the GC explicitly. My thought was simply to 
stop preloading before GC begins (or at least *when* GC begins).

You mean that LablGTK directly invokes the garbage collector after 10 
images. That's not much (unless, of course, they are big images). Sounds 
like it's a lot of trouble for a small benefit.
