Log Message:
-----------
IO.open(path) will handle a file descriptor when path is numeric.

Test Script:
{{{
require 'test/unit/assertions.rb'
include Test::Unit::Assertions

FILE = "tmp.xxxx.txt"

f1 = File.open(FILE, "w+")
f1.puts "hello world!"
f1.pos = 0
f2 = File.open(f1.fileno)

assert_equal(f1.fileno, f2.fileno)
assert_equal("hello world!\n", f2.read)
assert_raise(Errno::EBADF) { File.new(30000) }

puts :ok
}}}
