Indeed, I noticed that ;-)

The only comment I could find from a MySQL employee suggested that.
But I don't believe them. There are no other network problems visible,
and the 'authorization packet' is mid-way through the connection setup
(i.e. the TCP/IP connection has already been successfully used to both
send and receive data if we get as far as the 'authorization packet').
I suspect some sort of bug in the MySQLd authentication code.

I've managed to discover using --debug that it's due to MySQLd failing
to handle EINTR from read() in the authentication stage.

I've filed a bug report: http://bugs.mysql.com/bug.php?id=28359

Does anyone know how/where to best attract the attention of a MySQL
developer to this bug?
