[Bug 514322] [NEW] Ruby 1.9.1 leaks memory when using Module.include

[MiiJaySung]

Public bug reported:

Binary package hint: ruby1.9.1

I've discovered, along with a handful of others that Ruby 1.9.1 leaks
memory when using Module.include

This is major issue for those using Ruby in an persistent environment
(i.e. Rails processes which are typically daemonised) as the host
machine will probably run out of memory.

A simple test-case is: ruby -e 'loop { Module.new.extend Module.new }'

I've nudged the Ruby developers upstream about this over here:

http://redmine.ruby-lang.org/issues/show/1392

There is now a patch (pending as I speak) which is going to be committed
to the 1.9.2 trunk.

Given that it looks like lucid is still working from 1.9.1, and there
will be Karmic users utilizing Ruby 1.9.1 it would be highly desirable
if this can be back-ported to Lucid and Karmic.
