+<p>This extension allows plugins to have a non-realtime worker method, with
+thread sychronisation and communication issues handled by the host.  This
+allows plugins to perform non-realtime actions (such as loading files) using a
+simple and portable API without having to worry about the complexities of
+multi-threading.</p>
+
+<p>Because the worker thread is implemented by the host, many plugins can share
+the same thread and communication buffers, which reduces bloat and fixed
+per-plugin buffer size limitations.  The host has the power to implement
+threads in a suitable way, while plugins are simpler and thus less
+error-prone.</p>
+
+<p>This interface is designed to gracefully handle single-threaded synchronous
+execution, in which case the host may simply run all work immediately.  This
+makes it possible for the same plugin code to work with sample accuracy for
+offline rendering, or in real-time with non-real-time work taking place in a
+separate thread.</p>
