+Subject: Bug 1376873 - Reduce thread stack size in platform_thread.cc; r=bwc
+
+Summary:
+The current default stack size of 1M results in intermittent OOMs on win32
+builds while running web-platform tests. The value of 256k was chosen for
+consistency with the default value used elsewhere in Gecko, which is defined in
+nsIThreadManager.idl.
