dns.lua:226: bad argument #1 to 'randomseed' (integer expected, got number)

What steps will reproduce the problem?
1. /etc/init.d/prosody start
2. tail -f /var/log/prosody/prosody.err
3. Connect to prosody with a Jabber client and try to join a room on a remote 
server.

What is the expected output? What do you see instead?
The error below is not fatal, but it seems to keep s2s from working. This is 
similar to issue #320.

What version of the product are you using? On what operating system?
I am using prosody 0.9.4 on OpenWrt/Linux/32-bit MIPS. Lua versions in use are:

liblua: 5.1.5
lua: 5.1.5
luaexpat: 1.3.0
luafilesystem: 1.6.2
luasec: 0.4
luasocket: 3.0-rc1-20130909

Please provide any additional information below.
In dns.lua, I temporarily changed:

math.randomseed(math.floor(10000*socket.gettime()) % 0x100000000);

to:

math.randomseed(math.floor(10000*socket.gettime()) % 0x10000000);

Removing a digit from the modulus operand made the problem go away.
