unwind-protect is indeed a Common Lisp form, not Clojure. It ensures
that a given piece of code is always executed, even when an error or
some other condition causes the code to exit early.
In Clojure (and Java), the nearest equivalent is the try-catch-finally
block. It looks like this:
(try
... code that may throw an exception ...
(catch Exception ex
... handle an exception ...)
(finally
... always do this, no matter what ...))
The "finally" block is always guaranteed to run, barring some
catastrophic failure like the JVM crashing.
