The DDC1 and int10 code are blocking SIGIO to get some assurance that their usleep() calls take as long as they expect. That's a good start but you really want to be blocking more than just SIGIO, SIGALRM too at minimum. At this point, except for SIGIO handler setup itself, BlockSIGIO really means "block input events". Reviewed-by: Tiago Vignatti <tiago.vignatti@nokia.com> Signed-off-by: Adam Jackson <ajax@redhat.com>
