Recover application after it becomes unresponsive

Is there any way to recover an application once it freezes aside from killing it? --- Context being, I have been working on a couple of files in TextMate 1.5 and TextMate has stopped responding, I have not saved these files, and I really do not want to loose the work. I've killed all other running applications and have let the computer idle for quite some time but TextMate still remains unresponsive. Before it froze I was conducting a simple regex search query within TextMate. The files were only about 2kb in size.
