This looks like the perfect opportunity to send this conversation way
into technical land.

Consider the following presentation and then GC system:
Joe Damato does a great job explaining GC under Ruby.
http://timetobleed.com/garbage-collection-and-the-ruby-heap-from-railsconf/

I have also been reading up on a GC system called Schism- a real-time,
concurrent  non-moving, non-copying GC for java. I contacted the
university listed as being a collaborate on this Schism. Sadly it is
proprietary.
 However, if I could ever free up some time, I was going to check how
patent encumbered it is. If the road is clear, then this would be a
great thing to have in ruby.

For those who don't know, GC is often blamed- generally rightly so-
for the biggest reason why ruby is slow.

I have no affiliate with either of these links.
