#243: GC in callbacks will invalidate references to Scheme data used in "crunch"

Component:  extensions  |     Version:     
 Keywords:  crunch      |  
------------------------+---------------------------------------------------
 When code compiled with `crunch` manipulates number-vectors or strings
 allocated in Scheme, then a callback is likely to trigger a GC, which will
 move those data-structures, rendering existing references to them on the
 crunch side invalid.

 It may be possible to use a special vector/buffer type for data-objects
 passed from Scheme to crunch.
