As always the case, this problem have been encountered and solved! Your 
code is exactly what I needed. However, I was too impatient to wait for 
your reply. :-) I have realized the problems of arraymodule.c and added 
a ob_ownmem member in the object structure. Existing operations have 
been modified (mostly unchanged) according to this flag and the new 
module works well.

Thank everyone for the help. especially in thie new year's day.
