Neither is impacted. In the new function spawn_pinger(), we use
fsockopen to start a new thread via HTTP. AFAIK it's the only
platform-independent way to do this without involving the user agent.

If you are concerned that some hosts block fsockopen, don't worry:
pings and trackbacks depend on the exact same function. If
spawn_pinger() fails, execute-pings.php wouldn't have worked anyway.
