----------------------------------------
Feature #5665: [PATCH] io.c (rb_io_fsync,rb_io_fdatasync): release GVL
http://redmine.ruby-lang.org/issues/5665

Author: Eric Wong
Status: Open
Priority: Low
Assignee: 
Category: core
Target version: 2.0.0


fsync() and fdatasync() may take a long time on slow disks and/or
if there is much dirty data.


Also pullable via git: git pull git://bogomips.org/ruby.git fsync-nogvl

(Once in a while I'll actually care to fsync(), most of the time I can't
 stand it and even use libeatmydata :)
