Subject: [PATCH] Set chunk size to 64 KB

Still, this is an arbitrary choice. But as send_long_data() is designed
to send out data to the network immediately, it is probably a good thing
performance-wise to have a little bit bigger chunks (think TCP windows
or offloading). And, on the other hand, 64 KB of memory in PHP should
not hurt that much.
