Socket#gets and Socket#puts

We really ought to think about documenting the Socket class tree. :)

Okay, I'm learning with a little "Trial by Fire" over here. I'm
building a threaded server. I'm using Socket#gets for reading and
that's going fine. I've learned that it returns nil, when the
connection is closed. Does it throw exceptions under any conditions
and if so, which ones?

What about Socket#puts? If it's waiting to send something, what
happens if the connection is closed? Should I expect any exceptions on
this end of the equation?

Thanks.

Solving a little of my own puzzle here, Socket#gets and Socket#close
both throw IOError, if the Sockect is already closed.
