From 7edc02f4deedb3a11abeb328dc2596b2886c2f47 Mon Sep 17 00:00:00 2001 From: Erik Faye-Lund Date: Fri, 17 Jan 2014 15:17:09 +0100 Subject: [PATCH] prefer xwrite instead of write Our xwrite wrapper already deals with a few potential hazards, and are as such more robust. Prefer it instead of write to get the robustness benefits everywhere.
