+	    A simple socket API is provided through the socket
+	    module. This is a low level API that does *not* replace
+	    gen_[tcp|udp|sctp]. It is intended to *eventually*
+	    replace the inet driver, but not the high level
+	    gen-modules (gen_tcp, gen_udp and gen_sctp). It also
+	    provides a basic API that facilitates the implementation
+	    of other protocols, than TCP, UDP and SCTP. </p>

+	    This means that a terminating process will yield and
+	    possibly be suspended on busy distribution entries while

+	    <p>Previously, all ETS tables used centralized counter
+	    variables to keep track of the number of items stored and
+	    the amount of memory consumed. These counters can cause
+	    scalability problems (especially on big NUMA systems).
+	    This change adds an implementation of a decentralized
+	    counter and modifies the implementation of ETS so that
+	    ETS tables of type <c>ordered_set</c> with
+	    <c>write_concurrency</c> enabled use the decentralized
+	    counter. Experiments indicate that this change
+	    substantially improves the scalability of ETS
+	    <c>ordered_set</c> tables with <c>write_concurrency</c>
+	    enabled in scenarios with frequent <c>ets:insert/2</c>
+	    and <c>ets:delete/2</c> calls.</p>
