Thank you, this answers my question. I did not state it clearly, but I
was interested in deallocating memory from the computer process, not
just releasing the array into NCL's free space, which I am sure is
working as you say.
If you don't mind me saying so, this might be good for a footnote in the
delete function doc page.
