Trying to figure out what I am doing wrong.  
Whenever I run this code it starts using up all my ram but no process  
shows up as using the ram but the task manager shows ram usage going up  
until the computer starts hanging.

are you suppsoed to save the cairo context and use the same one over and  
over again or run this line of code every time you draw?

cr = window.create\_cairo\_context

here is the simple program I started with and it hangs my computer if I  
let it run for a minute or two.

switched ruby version with rvm to 1.9.3 from 2.0 and installed the  
previous version of gtk2 on 1.9.3 and now it seems to work.

I have tested your code on Windows, with Ruby 2.0.0 p0, with gtk 2.0.2,  
and  
haven’t ran into any issues with memory leakage.
