PR_Poll() and non-blocking sockets?

Hi,

I am attempting to use PR_Poll() in a server application to poll a collection of non-blocking sockets (which have been accepted using PR_Accept())  The problem is, no matter what I do, the call to PR_Poll() always returns immediately indicating the socket is readable.

Is this the normal behavior?  Will PR_Poll() never pause for any length of time with non-blocking sockets?  I don't want to be hogging CPU at 100% if it's not necessary.

I have searched for solutions online.  I have already been through the exercise of calling PR_GetConnectStatus() and PR_Poll() with write|exception to ensure that the socket gets fully established (and in fact this was part of the problem)

So now I have an incoming PR_Accept()ed socket, which PR_GetConnectStatus() says is good, and I PR_Poll() it (with PR_POLL_READ) and it always returns true.

This is all from the server's point of view.  All sockets including the bind/listen sockets are non-blocking.

Am I missing a step?  or is this normal?

Thanks.
