Description Cameron Zwarich (cpst) 2008-10-09 20:18:48 PDT 
Loading Safari, launching a new window (which is blank on my machine), going to about:blank, closing the window and then quitting Safari gives 5 StructureID leaks. I will post GDB traces of StructureID allocation and deallocation.

The number 5 does not increase if we close and reopen about:blank.

I ran a script to figure out which ones "leaked":

Leaked StructureID 0xe6afd0
Leaked StructureID 0x1390d620
Leaked StructureID 0x139113d0
Leaked StructureID 0x1396bc30
Leaked StructureID 0x13ddd830

These are the 5 allocated by JSGlobalData.
