Unfortunately, this patch won't work - it's not just DecoratorTools 
that would have to change, it's every library that *uses* DecoratorTools.  See:

for more info.

(As a workaround, have you tried compiling the bytecode for affected 
modules with -O, and then running the interpreter with -OO?  A bit 
hacky, but if you're that desperate for memory...  what sort of 
system are you building, anyway, where docstrings are a significant 
part of your memory footprint?)
