Subject: [PATCH] qemu-kvm: Fix test for I/O thread
Date: Fri, 18 Jul 2008 10:10:15 +0200	[thread overview]
Message-ID: <48804FE7.4090507@siemens.com> (raw)

Looks to me like this was rather intended. But given that 4e8b8a6d92c5ece048e65be3a3980d24f065b32b claims to actually fix a bug in
its original broken form, please have a careful look.
