I would be interested to hear about any solution in this vein as well.
It seems to boil down to this: can the byte buffer that backs Ruby
strings be exposed for direct use by C functions?  If not, then this
discussion can only move on to alternatives.  If it can be done, how so?

Could this even be done safely without some form of cooperation from the
GC?  That byte buffer could potentially be moved around at any time
during a GC event, couldn't it?
