   Priority:    Low.  Nothing is broken.  This is an enhancement that would
                improve the OS design and possible reduce some FLASH usage
 
+  Title:       UNIFIED DESCRIPTOR REPRESENTATION
+  Descripton:  There are two separate ranges of descriptors for file and
+               socket descriptors: if a descriptor is in one range then it is
+               recognized as a file descriptor; if it is in another range
+               then it is recognized as a socket descriptor.  These separate
+               descriptor ranges can cause problems, for example, they makes
+               dup'ing descriptors with dup2() problematic.  The two groups
+               of descriptors are really indices into two separate tables:
+               On an array of file structures and the other an array of
+               socket structures.  There really should be one array that
+               is a union of file and socket descriptors.  Then socket and
+               file decriptors could lie in the same range.
