Can't detect EOF with pylibpcap

[Grant Edwards]

I'm using pylibpcap 0.4 to analyze capture files created by
Ethereal.  It works nicely except I can't detect end of file.

When you use the next() method, it just never returns when it
hits end of file.  Calling dispatch() or loop() returns without
doing anything, but neither return the number of packets
processed, so there's no simple way to determine if you're at
end of file or not.  The C versions of the dispatch() and
loop() calls return the number of packets processed (0 == EOF).

Has anybody else figured out how to detect EOF with pylibpcap?
