We intend to do two things about this. We'd like to move packet capturing
from libpcap to wiretap. Once we do that, we can control the filter
language. Secondly, we want to provide a GUI for creating filters. The
GUI would allow users to forget about the underlying filter syntax.

Yes, the linux libpcap has problems with timeouts when no packets arrive.
See the "README.linux" file for a fix which requires patching and
re-compiling libpcap.
