+ <p>Lock counting can now be fully toggled at runtime in
+ the lock counting emulator (<c>-emu_type lcnt</c>).
+ Everything is enabled by default to match the old
+ behavior, but specific categories can be toggled at will
+ with minimal runtime overhead when disabled. Refer to the
+ documentation on <c>lcnt:rt_mask/1</c> for details.</p>
