I've tried this before and it didn't work out so well.  The order in which you 
free them becomes very important and error prone.  

And, of course, whatever solution you make has to be optional and easy to 
maintain as the default policy in WebKit is to not care - by design - about 
cleaning up after static globals on exit as that is left to the OS.

Another strategy for the embedded case where you want to free everything on 
exit is to create a custom memory handler that will do this for you.

Cheers,
Adam
