I think he has already understood that thrashing swap is
a
bad idea. He just did not understand why allocating a
16GB
array took so long on a system with 16GB RAM. I explained
why 8GB is the practical limit to array size.


Andy,
You got me scared with that one but as far as I can tell
that copy mechanism is not used. For testing it I created
with no problems a zeros() array only slightly smaller than
the available largest memory chunk. If that copy thing had
been there I would have get an Out of Memory ... bla, bla,
bla error.
