Backport #2560

=begin Consider the following: File.open('test_file', 'wb') { |f| f.write 'abc' } IO.read('test_file', 0, -1) rescue nil File.unlink('test_file') On Windows the unlink call fails with: `unlink': Permission denied - test_file (Errno::EACCES) This is due to fact that IO.read, invoked with invalid offset parameter does not close the opened file. But the documentation clearly states that: "read ensures the file is closed before returning." This causes two RubySpec failures for IO.read: mspec -t r core\io\read_spec.rb ruby 1.9.2dev (2009-11-12 trunk 25723) [i386-mingw32] ..........E..E..................E. 1) An exception occurred during: after :each IO.read raises an Errno::EINVAL when not passed a valid offset ERROR Errno::EACCES: Permission denied - D:/work/jruby-dev/rubyspec.git/rubyspec_temp/io_read.txt D:/work/jruby-dev/rubyspec.git/core/io/read_spec.rb:13:in `block (2 levels) in <top (required)>' D:/work/jruby-dev/rubyspec.git/core/io/read_spec.rb:5:in `<top (required)>' D:/work/jruby-dev/mspec.git/bin/mspec-run:8:in `<main>' 2) An exception occurred during: after :each IO#read can be read from consecutively ERROR Errno::EACCES: Permission denied - D:/work/jruby-dev/rubyspec.git/rubyspec_temp/io_read.txt D:/work/jruby-dev/rubyspec.git/core/io/read_spec.rb:100:in `block (2 levels) in <top (required)>' D:/work/jruby-dev/rubyspec.git/core/io/read_spec.rb:88:in `<top (required)>' D:/work/jruby-dev/mspec.git/bin/mspec-run:8:in `<main>' =end
