The problem is that the packet number is completely ignored in PyMySQL:
http://forge.mysql.com/wiki/MySQL_Internals_ClientServer_Protocol#The_Packet_Header

Payloads larger than 16Mb should be split in at most 16Mb packets and sent sequentially incrementing the packet number.

We found the problem while working on the SSL patch, but at the times fixing this was out of our scope.

Here's a patch fixing the issue.

Please note that for the test to pass you probably need to tweak max_allowed_packet in your my.cnf (defaults to 16Mb)

Thanks Evax. Rolled your patch into r43. Also tweaked the unit test to instead < 1 mb.
