+ Ets table type ordered_set could order large integer keys
+ wrongly on pure 64bit platforms. This is now corrected.</p>
+ <p>
+ Own Id: OTP-9181</p>
+ </item>
+ <item>
+ <p>
+ The status of a process was unnecessarily set to waiting
+ before a process was enqueued in a run queue. This bug
+ was harmless up until OTP-R14B01. In OTP-R14B02
+ <c>erlang:hibernate/3</c> was fixed (OTP-9125). After the
+ introduction of OTP-9125, the previously harmless process
+ status bug sometimes caused erroneous badarg exceptions
+ from <c>process_info()</c>.</p>
+ <p>
+ OTP-9125 also introduced a thread unsafe access to the
+ status field of a process which now also have been fixed.</p>
