title: showAsAction="ifRoom" doesn't show the item even when there is plenty of room
body: <p>I am trying to get the ActionBar working properly on my app (and I'm using ActionBarSherlock to get a unified UI between Android 2.x and 4.x). </p>
  
  <p>I feel like <code>android:showAsAction="ifRoom"</code> is just a big, fat lie. Whenever I set an action to <code>ifRoom</code> it ALWAYS shows up in the overflow menu even if there is PLENTY of room. Here are two screenshots from the same emulator. The first shows the ActionBar with all options set to <code>always</code> and the second shows the ActionBar with the last two options set to <code>ifRoom</code>. As you can see, there was PLENTY of room when they were all shown in the <code>always</code> screenshot, so why aren't they all showing in the second because they DO have room?</p>

  <p>Here is my menu.xml:</p>
  
  <pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt;

          android:showAsAction="always"
          android:title="Add"/&gt;
      &lt;item
          android:id="@+id/calculateNPV"
          android:icon="@drawable/menu_icon_npv"
