+ A process could end up in an inconsistent half exited
+ state in the runtime system without SMP support. This
+ could occur if the processes was traced by a port that it
+ also was linked to, and the port terminated abnormally
+ while handling a trace message for the process.</p>
+ <p>
+ This bug has always existed in the runtime system without
+ SMP support, but never in the runtime system with SMP
+ support.</p>

+ Removed unnecessary copying of data when retrieving

+ Changed default OS monotonic clock source chosen at build
+ time. This in order to improve performance. The behavior
+ will now on most systems be that (both OS and Erlang)
+ monotonic time stops when the system is suspended.</p>
+ <p>
+ If you prefer that monotonic time elapse during suspend
+ of the machine, you can pass the command line argument
+ <c>--enable-prefer-elapsed-monotonic-time-during-suspend</c>
+ to <c>configure</c> when building Erlang/OTP. The
+ configuration stage will try to find such a clock source,
+ but might not be able to find it. Note that there might
+ be a performance penalty associated with such a clock
+ source.</p>

+ The <c>configure</c> command line argument
+ <c>--enable-gettimeofday-as-os-system-time</c> has been
+ added which force usage of <c>gettimeofday()</c> for OS
+ system time. This will improve performance of
+ <c>os:system_time()</c> and <c>os:timestamp()</c> on
+ MacOS X, at the expense of worse accuracy, resolution and
+ precision of Erlang monotonic time, Erlang system time,
+ and OS system time.</p>
