This is leaking a ton of stuff, including what looks like the cycle collector object itself.  I'm not really sure what is going on.  I'd expect a leak this severe to show up with our regular leak detector, so keep an eye out for a new intermittent leak in debug builds.

[Andrew McCreight [:mccr8]]

Oh, sorry, we're leaking CollectorData, which is the chunk of data we store in TLS to keep around the cycle collector.

[Andrew McCreight [:mccr8]]

This happened once a few months ago, so I'm going to close this as WFM.
