ST2 will become completely unresponsive when performing some searches. I can reproduce it consistently with a project containing Bash scripts. ST2 will likewise hang when reopening, requiring deletion of Session.sublime_session.
1. Grab this repo and open it in Sublime: https://github.com/sstephenson/rbenv
2. Do a "Find in Files", enter something that will hit many files, eg. "e". (Make sure "Show Context" and "Use Buffer" are enabled.)
3. ST2 will now hang indefinitely, and must be force-quit.
I did a sample of a hanging process here: https://dl.dropbox.com/u/12091499/Share ... e_hang.txt.
