I've done some additional experiments with this to find out exactly
where the stacksize becomes a problem.  It's fine as long as the limit
on the stacksize is <= 4194303 KiB,  but dies instantly if the stack
size is 4194304 KiB or higher.  This is the point where more than 32
bits are needed to store an address.

94)frell$ irb1.8
/usr/lib/ruby/1.8/irb/context.rb:77:in `attr_accessor': stack level too
deep (SystemStackError)
