Thanks, but I will not apply thjis.

I'm in the process of resturcturing the whole environment handling.
The new implementation will use a hash table for internal storage, so
this code would no longer apply then.

Please wait a bit for me to publish the new code, and then try to
reimplement it in the new environment.

So thanks, but sorry...

Best regards,

Wolfgang Denk
