verify-socket-buffer is actually checking for an 8-bit subtag, and with this new-fangled unicode thing, that doesn't include strings.

My first inclination is to say that i/o on datagram sockets is done in octects. This requires the user to use encode-string-to-octects/decode-string-from-octets explicitly.

It might also be work to pay attention to the socket object's external format and encode the string on the user's behalf, but if Gilgamesh wants to send a cuneiform string "foo", then the actual buffer length in octets isn't going to be 3.

Upgrade to Ubuntu 10.04 LTS.

It looks like some exception flags get left on in the MXCSR somehow.
