Getting Clojure Stacktrace

I am aware of http://richhickey.github.com/clojure/clojure.stacktrace-api.html .

Is there a way to get the current stacktrace w/o throwing an exception and catching it?

(I'm debugging a piece of code, and want to capture stacktraces at certain points so I can analyze what's going on.)

Thanks!

This code return StackTraceElement array which is not so hard to turn in readable form: 

(.getStackTrace (Thread/currentThread))
