too short time-out

hi,

in your function

```
public function send($host, $port, $request, $responseLength = 1160) {
$response = '';
$fs = fsockopen($host, $port, $this->errorNumber, $this->errorString, 3);
...
```

the timeout delay of fsockopen seems to be too "short" : I have regulary some exception caused by this timeout.
maybe you should increase it to 5 or 10 (as WordPress Akismet plugin 2.5.6)

Search the PHP source for the public send($host, $port, $request, $responseLength = 1160) function and inspect its fsockopen call. Reproduce or review the timeout behavior, then verify that the selected longer timeout prevents the reported exceptions without breaking the Akismet request flow.
