Normally I would expect "ready for reading" to mean that it is open 
*and* there is some data that can be read.  Otherwise it does not really 
make sense to include such an fd in the set returned.

http://www.manpagez.com/man/2/select/

Having said that I do have experienced "ready for reading" returns if 
the other party of a TCP socket connection has closed the socket already 
resulting in a 0 byte non blocking read operation.  But that seems to be 
mostly related to the peculiarities of networks work.

So, under normal conditions select should block until data is actually 
readable (when using with a non empty set of descriptors you want to 
examine for readability, of course).  David's expectations are 
absolutely in line with what I would expect and as it turns out this 
seems to be a problem of a particular version only.

Kind regards
