For the record, this is a terrible solution, and the garbage collector keeps the memory usage to a few megabytes when JSReportExtraMemoryCost is used correctly, which is reasonable.

> Where is the extra reference to the JSContextRef coming from? Maybe the ref count is zero, but you're not sweeping anything so finalization never happens? Does the IncrementalSweeper work on Windows?
I'm not sure, but the ref count of the JSContextRef is always between 2 and 4.  Doing extra releases causes crashes, so there's probably something global that I wasn't expecting to be global.
