X-Received-From: 2a00:1450:4864:20::42f Subject: [Qemu-devel] [PULL 20/21] tests: use g_usleep instead of rem = sleep(time) X-BeenThere: qemu-devel@nongnu.org X-Mailman-Version: 2.1.21 Precedence: list List-Id: List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , Cc: =?UTF-8?q?Alex=20Benn=C3=A9e?= , qemu-devel@nongnu.org Errors-To: qemu-devel-bounces+importer=patchew.org@nongnu.org Sender: "Qemu-devel" X-ZohoMail-DKIM: fail (Header signature does not verify) Relying on sleep to always return having slept isn't safe as a signal may have occurred. If signals are constantly incoming the program will never reach its termination condition. This is believed to be the mechanism causing time outs for qht-test in Travis. The glib g_usleep() deals with all of this for us so lets use it instead.
