Subject: Disable semaphores fallback code for OpenBSD
Date: Thu, 27 Dec 2012 20:38:11 -0000
From: Brad <brad@comstyle.com>

Message-Id: <20121228063808.GC27232@rox.home.comstyle.com>
To: qemu-devel@nongnu.org

Disable the semaphores fallback code for OpenBSD as modern OpenBSD
releases now have sem_timedwait().
