Marc:

My code seems to be leaking memory, and, of course, after an hour or so of debugging I can't find the source, so, again, I'm wondering if it's the GC bug that could be causing this.

Such bugs are really insidious, even when they aren't the real cause of the problem, they distract the programmer from finding the real problem. And at least once the gc bug *was* the real problem, so it's hard to put it out of my mind ...

My program gradually increased its memory usage until it got over 16GB, at which point I killed it. After I tried a fix, I ran it again with a bit of instrumentation, and the file below gives a little information about the rate of growth in the leak.

This is with beta 22.
