+// The C++ spec dictates that allocation failure should cause the
+// (non-nothrow version of the) operator new to throw an exception.
+// Since we expect to have exceptions disabled, it would be more
+// appropriate (and probably standards-compliant) to terminate instead.
+// Historically failure causes null to be returned, but this define
+// allows switching to more robust terminating behaviour (that might
+// become the default at some point in the future). Note that any code
+// that wants null to be returned can (and should) use the nothrow
+// versions of the new statement anyway and is unaffected by this.
