This bug can be seen if you "open" more than 1 client locally, since the trying for bind() always goes from PORT_RANGE_START to PORT_RANGE_END the number of leaked file descriptors (socket, TCP) can be determined by the summation of (i - 1) for i in N:

for (int i = 1; i <= N; i++) { sum += i - 1; }

To get a high throughput I'm creating a lot of seeder clients, so I exhausted the number of fds rather quickly, heh.

Bitfield payload was truncated to the highest bit that was set. As a
consequence clients dropped the connection.

This is one of two changes required to resolve issues 91: download
resume not working
mpetazzoni#91
This change fixes a race condition in peer message exchange. First
incoming messages can be lost because incoming thread is started before
it is possible to register a message listener. There is a high
probability of missing the peer’s bitfield message immediately after
handshake and as a consequence downloads will not resume.
