Subject: [PATCH] doc/go1.1.html: state that the heap is bigger on 64-bit
 machines Be deliberately vague, since the precise details should not be
 depended upon. Fixes #5155.

+<h3 id="heap">Heap size on 64-bit architectures</h3>
+
+<p>
+On 64-bit architectures only, the maximum heap size has been enlarged substantially,
+from a few gigabytes to several tens of gigabytes.
+(The exact details depend on the system and may change.)
+</p>
+
+<p>
+On 32-bit architectures, the heap size has not changed.
+</p>
+
+<p>
+<em>Updating</em>:
+This change should have no effect on existing programs beyond allowing them
+to run with larger heaps.
