Thanks for the data.  System.Pool_Size.Allocate
is called a lot by Work_On_12 and Work_On_18.
I don't know how to change that.  Still it has led
me to another idea---but that should not delay submitting
Knucleotide any further:

http://home.arcor.de/bauhaus/Ada/knucleotide.multi.gnat

Should I?  Are there any objections?

***

That idea will require that some essential parts be
rewritten, so please ignore it for the moment:

1/ enumerate the characters we are looking at in a type,
2/ pack them into 4 bits each (a representation)
3/ write new hash function...
4/ optionally, do (3) for fragments of length 12 and 18 only

The idea is that the packing, by assumption,
can decrease the number of times System.Pool_Size.Allocate
is called (which seems to involve the threading library
a lot, too).
