- * The map entries can *almost* be read with programs like cat.  However,
- * large maps need special programs to read.  It is not easy to implement
- * a program that can sense the required size of the buffer, and then
- * subsequently do a read with the appropriate size.  This operation cannot
- * be atomic.  The best that we can do is to allow the program to do a read
- * with an arbitrarily large buffer, and return as much as we can.  We can
- * return an error code if the buffer is too small (EFBIG), then the program
- * can try a bigger buffer.
