This feels like more code than it needs to be. How about:

log_string += browser_processes[index].name + ASCIIToUTF16(", ") + ...

+    log_string.append(ASCIIToUTF16(", "));
+    log_string.append(base::Int64ToString16(aggregate.working_set.priv));
+    log_string.append(ASCIIToUTF16(", "));
+    log_string.append(base::Int64ToString16(aggregate.working_set.shared));
+    log_string.append(ASCIIToUTF16(", "));
+    log_string.append(base::Int64ToString16(aggregate.working_set.shareable));
   }
   if (log_string.length() > 0)

Done.
