+ <list>
+ <item>
+ <p>Introduced support for eager check I/O.</p>
+ <p>By default eager check I/O will be disabled, but this
+ will most likely be changed in OTP 18. When eager check
+ I/O is enabled, schedulers will more frequently check for
+ I/O work. Outstanding I/O operation will however not be
+ prioritized to the same extent as when eager check I/O is
+ disabled.</p>
+ <p>Eager check I/O can be enabled and disabled using the
+ <c>erl</c> command line argument <seealso
+ marker="erl#+secio"><c>+secio</c></seealso>.</p>
+ <p>Characteristics impact when enabled:</p> <list>
+ <item>Lower latency and smoother management of externally
+ triggered I/O operations.</item> <item>A slightly reduced
+ priority of externally triggered I/O operations.</item>
