Comment (by sjamaan):

 This version applies the ideas I mentioned, and it results in exactly the
 same performance as with regular CHICKEN when **not** collecting symbols.

 Unfortunately, collecting weak symbols is very slow.  The `knucleotide`
 benchmark is five times slower than with the old CHICKEN, when passing
 `-:w`.  Of course, this **can** be explained due to the fact that the old
 CHICKEN only reclaimed a few hundred symbols in major GCs on that
 benchmark while CHICKEN with patch reclaims several **hundred thousand**
 symbols.
