+    ** This file contains code to support the concept of "benign"
+    ** malloc failures (when the xMalloc() or xRealloc() method of the
+    ** sqlite3_mem_methods structure fails to allocate a block of memory
+    ** and returns 0).
+    **
+    ** Most malloc failures are non-benign. After they occur, SQLite
+    ** abandons the current operation and returns an error code (usually
+    ** SQLITE_NOMEM) to the user. However, sometimes a fault is not necessarily
+    ** fatal. For example, if a malloc fails while resizing a hash table, this
+    ** is completely recoverable simply by not carrying out the resize. The
+    ** hash table will continue to function normally.  So a malloc failure
+    ** during a hash table resize is a benign fault.
