Comment 7 for bug 10821

Here, a quick trace of hald shows that it polls the cdrom drive every two
seconds or so:

20:58:51 gettimeofday({1106618331, 708401}, NULL) = 0
20:58:51 poll([{fd=6, events=POLLIN}, {fd=9, events=POLLIN}, {fd=13,
events=POLLIN|POLLPRI}, {fd=10, events=POLLIN}, {fd=8, events=POLLIN}], 5, 1990) = 0
20:58:53 gettimeofday({1106618333, 697901}, NULL) = 0
