Your post gave me an idea already, so far we've only been 
focusing on Throwable, however... the solution for Error:s and 
Exception:s is actually asymmetric!

For the vast majority of applications the best possible 
implementation for Error:s is to simply leak the memory, this is 
definitely not true for Exceptions(but it could be true for a 
small subset of applications, short-lived tools).
