That was my first thought, but the Windows Task Manager showed no
increase in the amount of memory used (and I was loading >100 MB of
images total) and there was not a lot of disk activity, which I always
see when it's swapping to/from disk. There isn't any method in the
plugin like the one you described.

I thought maybe since I was calling the plugin repeatedly, the garbage
collector just wasn't getting around to releasing some used objects, so
I tried adding a System.gc() call at the end of each loop of my plugin,
but that didn't help.
