With strace, when I do nothing on the gtk screen, we get
what is under, it seems that the poll has a 5000 milli-sec
timeout, but takes 10 sec to wake.
When I move the mouse on the gtk screen, there are too many
events on the screen to see anything but I can send it if you
need it.
gettimeofday({1203026980, 431960}, NULL) = 0
poll([{fd=3, events=POLLIN}], 1, 5000) = 0
gettimeofday({1203026990, 459054}, NULL) = 0
gettimeofday({1203026990, 459250}, NULL) = 0
write(1, "1203026990\n", 111203026990
) = 11
read(3, 0x809e004, 4096) = -1 EAGAIN (Resource
temporarily unavailable)
gettimeofday({1203026990, 459871}, NULL) = 0
poll([{fd=3, events=POLLIN}], 1, 5000) = 0
gettimeofday({1203027000, 470939}, NULL) = 0
gettimeofday({1203027000, 471136}, NULL) = 0
write(1, "1203027000\n", 111203027000
) = 11
