A cell in guile (see also guile's manual) is one memory object (one used 
variable or value, or one pointer to a more complex structure). Basically, 
think of them as "memory used".

They are not called Bytes or memory, because 1) each cell is a double word and 
2) while for simple variables like a number they directly store the value, for 
more complex objects, they only store a pointer and you don't know how much 
memory is really needed by that scheme object.

Cheers,
Reinhold
