ok I've gotten to the point where I've tidied it up, added separate 
handle types for libraries and code within the library, and added a few 
modes that where missing (I am waiting to finish the adainit & adafinal 
calls and write an example before I email you sk).  Now I'm in the 
process of writing nice tidy calls to adainit & adafinal - code that 
will be called over and over - and am a bit confused.

Should I use ada.unchecked_conversion (which works in the example) or 
system.address_to_access_conversion?  (or something else entirely?).

I was going to use an address_to_access_conversion but wouldn't that 
give an access to an access to a procedure for the following type?

type Procedure_Access is access procedure;


The package instantiation would be

package X
    is new System.Address_To_Access_Conversion (Procedure_Access);


What's the best way to do the conversion so the procedure can be called? 
  In the meantime I will stick with Unchecked_Conversion, which works 
*here* even if it's a bit risky.
