Subject: [ruby-talk:6459] question about memory usage of a script

The following script uses more memory as N gets bigger.  Should I
expect it to run in constant space?  If not, what do I need to know to
understand how the GC reclaims memory?  I'd like to know, so I can get
an idea of the memory usage of a long-running process, like a server
written in Ruby.

Cheers,
Doug

#!/usr/local/bin/ruby
N = Integer(ARGV.shift || 1)
def test()
    li1 = (1..10000).to_a
    li2 = li1.slice(0, li1.length)
    while (not li2.empty?)
	li1.push(li2.shift)
    end
end
for i in 0 .. N
    test()
end
