             nThis:


The code

for (var id in (new Array)) { }

leaks 13 StructureIDs (in addition to the ones in JSGlobalData) the first time
you load it, and then it leaks 2 more every time you load it. The code

for (var id in (new Object)) { }

leaks 11 StructureIDs the first time you load it, but does not leak any more
when you load it again.
