+/**
+ * Manages the UNO thread pool factory.
+ *
+ * <P>The thread pool factory is a process-wide resource.  It is important that
+ * all UNO environments within a process share the same thread pool mechanisms:
+ * if a synchronous UNO call is bridged out from one local UNO environment over
+ * one remote bridge, and recursively calls back into another local UNO
+ * environment over another remote bridge, the code in the second environment
+ * should be executed in the thread that did the original call from the first
+ * environment.</P>
+ *
+ * <P>There are both a Java and a native thread pool factory.  A pure Java
+ * process will always use the Java thread pool factory.  A mixed process uses
+ * the system property <CODE>org.openoffice.native</CODE> (to be set by the
+ * native code that starts the JVM) to determine which implementation
+ * to use.</P>
