Nice thought. I think it would be too expensive if done for the first
instance, but for each of the backed-off instances it ought to be rare
enough that it's not a problem. So maybe something like:
## Generated each time a reporting threshold (10, 100, 1000, ...)
## is crossed, starting with 10.
event multiple_tcp_zero_windows(c: connection, is_orig: bool,
event multiple_tcp_checksum_errors(c: connection, is_orig: bool,
event multiple_tcp_retransmissions(c: connection, is_orig: bool,
