(truncate-file path [size-k]) PROCEDURE
Truncates or extends the given file so that it is size-k bytes
long, where size-k defaults to 0. If the file does not
exist, or if the process does not have sufficient privilege to truncate
the file, the exn:fail exception is raised.
WARNING: under Unix, the implementation assumes that the
system's ftruncate function accepts a long long second
argument.
