jerome - not sure that the code you provided fully answers the OP's
problem. I think you'd need to craft an http request and get a response to
really KNOW that the server is indeed responding. If you do that as a
replacement for where you have the "select {}" then I think you've got it.
Note, the http request need not be complicated. A simple "echo" style
handler would do the trick. As soon as you get the echo back then you know
your server is ready to start handling other types of potentially more
complex requests. If the server has a TON of stuff (seconds to minutes of
initialization) you can make the echo server wait till all the prelim's
are done first before sending the echo reply. After startup you can also
use the echo as a simple test of whether the server is at least running -
even if more complicated requests are failing.
