A week back I innocently updated Sinatra on an app which in turn updated Rack. Since then, I've had crazy hung passenger processes that just gobble up CPU like it is going out of style.

After spending a few days trying everything I knew to to fix it, today I got help from a friend (Eric Lindvall) and dug in with strace, rbtrace, gdb, and gdb.rb and found the issue. Rack 1.3.0 tests a regex against a URL and it causes things to hang.

# This Gemfile is a cheat

# To use this you *MUST* symlink gems/gems to gems/ruby/1.8/gems etc.
# I recommend symlinking gems/gems gems/cache gems/specification gems/doc just to be sure
