fix for issue 3862: test_array fails FreeBSD 7 amd64

Browse source 
FreeBSD 7's underlying malloc() is behaves differently to earlier versions
and seriously overcommits available memory on amd64.  This may affect
other 64bit platforms in some circumstances, so the scale of the
problematic test is wound back.
