  <li>
    <code>CONFIG_NX_MXSERVERMSGS</code> and <code>CONFIG_NX_MXCLIENTMSGS</code>
    Specifies the maximum number of messages that can fit in
    the message queues.  No additional resources are allocated, but
    this can be set to prevent flooding of the client or server with
    too many messages (<code>CONFIG_PREALLOC_MQ_MSGS</code> controls how many
    messages are pre-allocated).

</ul>

<h2>Stack and heap information</h2>

<ul>
  <li>
    <code>CONFIG_BOOT_RUNFROMFLASH</code>: Some configurations support XIP
    operation from FLASH but must copy initialized .data sections to RAM.
  </li>
  <li>
    <code>CONFIG_BOOT_COPYTORAM</code>: Some configurations boot in FLASH
    but copy themselves entirely into RAM for better performance.
  </li>
  <li>
    <code>CONFIG_STACK_POINTER</code>: The initial stack pointer
  </li>
  <li>
    <code>CONFIG_IDLETHREAD_STACKSIZE</code>: The size of the initial stack.
    This is the thread that (1) performs the initial boot of the system up
    to the point where user_start() is spawned, and (2) there after is the
    IDLE thread that executes only when there is no other thread ready to
    run.
  </li>
  <li>
    <code>CONFIG_USERMAIN_STACKSIZE</code>: The size of the stack to allocate
    for the main user thread that begins at the user_start() entry point.
  </li>
  <li>
    <code>CONFIG_PTHREAD_STACK_MIN</code>: Minimum pthread stack size
  </li>
  <li>
    <code>CONFIG_PTHREAD_STACK_DEFAULT</code>: Default pthread stack size
  </li>
  <li>
    <code>CONFIG_HEAP_BASE</code>: The beginning of the heap
  </li>
  <li>
    <code>CONFIG_HEAP_SIZE</code>: The size of the heap
  </li>
