IO-extra

The methods are IO.closefrom, IO.fdwalk, IO#directio? and IO#directio=.

What is new in this release:

• Direct IO is now supported on Darwin, and some bugs in the directio methods have been fixed. Thanks go to Genki Takiuchi for the patches.
• Fixed a bug in fdwalk and closefrom when using Ruby 1.9.3 where closing reserved file descriptors would segfault the interpreter.
• Fixed a bug in the fdwalk method where it was not honoring the lowfd argument, and added a test for it.
• The rb_thread_call_without_gvl function is now used internally in place of rb_thread_blocking_region for Ruby 2.x.

What is new in version 1.2.0:

• Several Linux compatibility fixes.
• Now compatible with 1.9.x.
• Bug fix for IO.pread - memory leak and null byte behavior.
• Changed license to Artistic 2.0.
• Added test-unit 2.x as a development dependency.
• Several tests were updated to use features from test-unit 2.x.
• Fixed the 'example' rake task.
