Similar problem exists when I start tshark with -a duration:10 listening on an
interface with no cable connected. It seems, that the timeout is checked each
time a packet is recieved which is not good if there are no packets on the
wire. Strace says that it waits forever for recvfrom:

write(2, "Capturing on eth0\n", 18Capturing on eth0
)     = 18
time(NULL)                              = 1170610326
recvfrom(4,               

I think recvfrom() should be called within a select() loop with a timeout
defined. You could then check if the timeout elapsed each 0.5 sec or so.
