+ A timer internal bit-field used for storing scheduler id
+ was too small. As a result, VM internal timer data
+ structures could become inconsistent when using 1024
+ schedulers on the system. Note that systems with less
+ than 1024 schedulers are not effected by this bug.</p>
+ <p>
+ This bug was introduced in ERTS version 7.0 (OTP 18.0).</p>

+ Automatic cleanup of a BIF timer, when the owner process
+ terminated, could race with the timeout of the timer.
+ This could cause the VM internal data structures to
+ become inconsistent which very likely caused a VM crash.</p>

+ integer with the lowest <c>N*W</c> bits as zero and the
+ other operand not larger than <c>N*W</c> bits. <c>N</c>

+ Fixed implementation of <c>statistics(wall_clock)</c> and
+ <c>statistics(runtime)</c> so that values do not
+ unnecessarily wrap due to the emulator. Note that the
+ values returned by <c>statistics(runtime)</c> may still
+ wrap due to limitations in the underlying functionality

+ <p>
+ Fix performance bug in pre-allocators that could cause
+ them to permanently fall back on normal more expensive memory
+ allocation. Pre-allocators are used for quick allocation
+ of short lived meta data used by messages and other
+ scheduled tasks. Bug exists since OTP_R15B02.
