This not forgotten, but DOM is about to go away entirely thanks to Diego.  
When this bug still exists after DOM is gone, Ben Elliston's work to make 
edges a vector instead of a list will make it much much easier to fix this 
bug. 
 
This bug is the reason for a lot of slowness in various machine generated 
files, including insn-attrtab for example.
