Inconsistency in the socket options: Interesting socket behavior?

Question

I noticed that if I make a listening socket using SOCK_STREAM | SOCK_NONBLOCK, that the sockets I get after calling listener.accept() dont have the O_NONBLOCK flag set, but checking the result of gettimeout() on the same sockets gives me 0.0, which means they are non blocking. Why is this the case?

Comments

for which language or socket lib?
