+         When enabled, busybox will use the kernel sendfile() function
+         instead of read/write loops to copy data between file descriptors
+         (for example, cp command does this a lot).
+         If sendfile() doesn't work, copying code falls back to read/write
+         loop. sendfile() was originally implemented for faster I/O
+         from files to sockets, but since Linux 2.6.33 it was extended
+         to work for many more file types.
