+buffer_fromarray makes a virtual read buffer from an array.  The buffer
+reading functions will be able to read until the end of the data in the
+array, then signal EOF.  The buffer does not have its own buffer
+space, it reuses the one in the array.

+Do not touch the array until you are done with the buffer!
