Good point.  However, if the internal symbol table used weak references 
to Symbol objects,
all dynamic Symbols that are not pinned down by code could be garbage 
collected.

I have a weak reference implementation in C here that's portable to MRI 
1.8.7, 1.9 and REE: 
https://github.com/kstephens/ref/tree/master-mri-gc_api based on Brian 
Durand's "ref" gem
