+From eb905e0394045b84699511da402643f0fb53d923 Mon Sep 17 00:00:00 2001
+From: Kamal Mostafa <kamal@whence.com>
+Date: Thu, 17 Dec 2009 09:32:52 -0800
+Subject: [PATCH] Fix g_thread_create_posix_impl() crash for sched policy != SCHED_OTHER
+
+Capture the initial scheduling policy along with the initial priority,
+and create new threads using that policy, since the priority will not
+be valid otherwise.
+
+Fixes https://bugzilla.gnome.org/show_bug.cgi?id=599079 .
