So why are 2 lines missing when I change the blocking factor from 256 to
512? Even cat reads in 16k blocks... Also:

% dd if=3D/proc/net/ip_conntrack bs=3D512 | perl -ne 'print length()."\n"'
0+2 records in
0+2 records out
153
138
169
151
167
139

No line is longer than 256 chars, so why are 2 lines missing when I read
in 256 byte blocks?
