I'm working my way through writing an application using
the luaSocket library.

I'm using Lua 5.1 and luaSocket 2.0.1, and have compiled
and linked under MinGW - and so far things are working, but
I'm reviewing the code for possible race conditions.

My question has to do with potential race conditions in
the example on page 78 of the original PiL.

  The idea of using to wait until something
  interesting happens makes sense, but what happens if the
  socket became readable BETWEEN the original timeout and
  when is called?

  To make things more interesting, what if the socket never
  gets another character once is called?

  Does essentially block forever in this case?

I must add that it's surprising just how much functionality
you can build in just a few lines of Lua!
