-  Description: USB Mass Storage Memory Leak.  When examples/usbstorage is
-               built as an NuttShell (NSH) built-in, there appears to be a
-               memory leak that occurs when a USB mass storage connection is
-               established and then torn down.  This leak is 608 bytes each
-               time:

-   Priority:   Medium.  Obviously, this must be fixed.  However the USB 
-               Mass storage example is fine for supporting most development
-               needs even thought it does leak.
