Rails - Nov 2010 - Huge memory leak in benchmark.rb on converting to Rails 2.3.9

Am relatively new to ruby/rails and very new to low level stuff like
memory leaks.

Am trying to Rails 2.3.9 ( because of a compatibility issue with
firewatir-1.6.6 ) and the mongrel process grows _very_ quickly as soon
as it tries to render the page.

I''ve stepped into the code with Rubymine (ruby-debug-ide 0.4.6) and
narrowed things down to line 51 of action_pack/lib/action_controller/
benchmark.rb:

@view_runtime = Benchmark.ms { render_output render_without_benchmark(options,
extra_options, &block) }

Things hang here and the task manager shows the mongrel process
growing at roughly 40MB per second until I kill the process ( in
Rubymine debug )

Apparently render_without_benchmark is having issues.   And I''m having
trouble locating the def for render_without_benchmark.

The only change is the shift to Rails 2.3.9
The application is built with these components:

ruby 1.8.6 (2007-09-24 patchlevel 111) [i386-mswin32]
rails 2.3.5
watir 1.6.6
authlogic-2.1.3
bones-3.4.1
google-spreadsheet-ruby-0.1.1
mongrel-1.1.5-x86-mswin32-60
json-1.2.2
rack-1.0.1
roo-1.9.3
rufus-scheduler-2.0.6
spreadsheet-0.6.4.1
watirloo-0.0.8

The app also uses jquery and a number of YUI scripts

Hoping for help.

Update:
Had missed changing environment.rb to specify Rails 2.3.9.

Still having similar problem but the leak is only 3-4MB per
second... ;-)
Will keep looking to see what else I have missed.

Any suggestions would be most, most welcome!
