When cover instruments binary comprehensions it's generating a
{block, ...} abstract code term inside a {bc, ...} term that is causing
the evaluation to fail at runtime. Removing the block statement
eliminates the error.
The template of a bit string comprehension cannot have a counter since
it is not allowed to be a block.

LONG_LIVED is not thread safe on non-smp and
can only be used by scheduler.

perf counter is now part of the function pointer interface
and also the function returns the value instead of writing
to a memory buffer.

Microstate accounting is a way to track which state the
different threads within ERTS are in. The main usage area
is to pin point performance bottlenecks by checking which
states the threads are in and then from there figuring out
why and where to optimize.
Since checking whether microstate accounting is on or off is
relatively expensive if done in a short loop only a few of the
states are enabled by default and more states can be enabled
through configure.
I've done some benchmarking and the overhead with it turned off
is not noticible and with it on it is a fraction of a percent.
If you enable the extra states, depending on the benchmark,
the ovehead when turned off is about 1% and when turned on
somewhere inbetween 5-15%.

The perf_counter is a very very cheap and high resolution timer
that can be used to timestamp system events. It does not have
monoticity guarantees, but should on most OS's expose a monotonous
time.
A special instruction has been created for this counter to further
speed up fetching it.

ERTS_WRITE_UNLIKELY can be used to place global variables in
a specific section where only data that is very rarely modified
sits. This is used to improve cache locality.

When release_handler_1:get_supervised_procs/0 does a recursive walk of
the supervision tree, it calls sys:get_status/1 on supervisors, to check
if they are suspended or running.
This fixes a race condition where a list of supervisor pids is gathered,
one of them (legitimately) exits before release_handler can examine it,
then sys:get_status/1 is called with a dead pid, causing an exit(noproc)
See: http://erlang.org/pipermail/erlang-questions/2015-August/085712.html
(To recreate this problem for testing, I added a timer:sleep into the
release_handler_1 code, and killed a supervisor during
get_supervised_procs being called).
