+<p>This extension allows plugins to schedule work that must be performed in
+another thread.  Plugins can use this interface to safely perform work that is
+not real-time safe, and receive the result in the run context.  The details of
+threading are managed by the host, allowing plugins to be simple and portable
+while using resources more efficiently.</p>
+
+<p>This interface is designed to gracefully support single-threaded synchronous
+execution, which allows the same code to work with sample accuracy for offline
+rendering.  For example, a sampler plugin may schedule a sample to be loaded
+from disk in another thread.  During live execution, the host will call the
+plugin's work method from another thread, and deliver the result to the audio
+thread when it is finished. However, during offline export, the
+<q>scheduled</q> load would be executed immediately in the same thread.  This
+enables reproducible offline rendering, where any changes affect the output
+immediately regardless of how long the work takes to execute.</p>
