Thanks, his is great! I experimented with every way I could think of to put the transaction strategy into only the needed tests, but didn't realize there was this example.metadata[:js] trick. This should definitely be put into the docs for database_cleaner on github.

Man, this is super helpful! Just reduced by tests from 1 minute 8 seconds to 18 seconds! Thans so much :-D

This also fixed some other issues rspec+capybara-webkit was having as well. Thanks!

Cool!! Thanks!
