Preferences -> Variables
add this to the front of PATH: $HOME/.rbenv/bin:$HOME/.rbenv/shims:
set TM_RUBY to this: $HOME/.rbenv/shims/ruby
populate RBENV_VERSION with your version. example: 2.1.0-preview1
(and make sure the checkboxes for each of those variables is selected)

This all applies to Ruby 2.1. In some cases a setting is not available in 2.0, this is noted. There is also a different with 1.9, 1.8, and REE --- these are not noted.

All the relevant code is in https://github.com/ruby/ruby/blob/master/gc.c

RUBY_HEAP_MIN_SLOTS

default: 10000

The number of heap slots to start out with. This should be set high enough so that your app has enough or almost enough memory after loading so that it doesn't have to allocate more memory on the first request (althogh this probably isn't such a big deal for most apps).

(todo: figure out how big a slot is. i think the answer can be infered from this code.)

You'll need to clone https://developers.kilnhg.com/Code/Trello/Group/TrelloSimple/ (git or Mercurial) into your working directory that contains leaveClosedBoards.py
Get an api token

go here and get your Developer Key (ignore that token) https://trello.com/1/appKey/
visit this url, with your Developer Key inserted as shown https://trello.com/1/authorize?key=YOURDEVELOPERKEY&name=My+Application&expiration=1day&response_type=token&scope=read,write
grant access, and then get the token that is produced on the next page

You'll need to add a file in the same directory called settings.py that contains strings for MY_KEY, MY_TOKEN, and USER_TOKEN (USER_TOKEN can be an empty string)
Run the script with the last line commented out to see what boards you're leaving. When you're ready to do it for real, uncomment the last line.
