Not at the moment, and it's an entertaining way to break JRuby for fun 
and profit. I could add in the check for eval being aliased, and display 
a warning and deoptimize everything, but I currently do not because I've 
been waiting to see if any libraries break. So far, nobody does this.

The dynamic optimizations that will eventually go into place would check 
for this, so that if the methods seen previously suddenly change 
(aliased, redefined) the original code will be backed down.
