Well, the data cache is not any bigger than the code cache, so there 
will be cache thrashing in the data cache.  And the VM data (which is 
really code) will compete with the real data.

Compilers like VFX or iForth don't inline arbitrary long sequences, and 
also don't unroll loops; their code is pretty compact, more compact than 
a 32 bit ITC, and certainly more compact than a 64 bit ITC.
