It's unclear whether the java.io.RandomAccessFile class
actually creates a file in the filesystem.
The documentation (in section 21.23.1) says the constructor
`initalises a newly created RandomAccessFile by opening a connection
to an actual file, the file named by the path name `path' in the file
system'

If the file named by `path' does not exist, should the constructor
create it? Or should it throw an IOException? If it does create the
file in the file system, what modes should it use? What is the initial
file position?

In other words, what system call does
RandomAccessFile("./fred", "rw")
map onto?
open("./fred", O_RDWR) ?
or
open("./fred", O_RDWR|O_CREAT, 0666) ?
or what?
