Hi Again

Just did a quick non scientific look at the memory growth when running an
Rtalk application.  30K methods generated for 15K callsites gave 2-3K 
bytes per method
generated.  Part of this is that jvm bytecodes which are also generated on 
fly (starts from Rtalk bytecodes).  Lambda forms appear to be just under 
half of the memory
