Thanks for the benchmark results.

Essentially the same performance trick has been in 
database.e for more than a year now:

mem = allocate(4)

procedure put4(atom x)
-- write 4 bytes to current database file
-- x is 32-bits max
    poke4(mem, x) -- faster than doing divides etc.
    puts(current_db, peek({mem, 4}))
end procedure

I accept that you can copyright the 
specific routines and benchmarks that you just posted.

I don't accept that you can restrict the use of this trick
by myself or anyone else.  I may eventually rewrite
int_to_bytes() and similar routines using this method.
