2011-05-03qemu-progress.c: printf isn't signal safeJes Sorensen1-1/+6
Change the signal handling to indicate a signal is pending, rather then printing directly from the signal handler. In addition make the signal prints go to stderr, rather than stdout. Signed-off-by: Jes Sorensen <Jes.Sorensen@redhat.com> Signed-off-by: Kevin Wolf <kwolf@redhat.com>
