+
+  o Enable a "pull" interface. The application that uses libcurl decides where
+    and when to ask libcurl to get/send data.
+
+  o Enable multiple simultaneous transfers in the same thread without making it
+    complicated for the application.
+
+  o Enable the application to select() on its own file descriptors and curl's
+    file descriptors simultaneous easily.
+
