Don't have time for a test case right now; but I've checked the code and 
remembered (parts of) the problem:

1) If you're using non-blocking SSL streams then fread sometimes returns 
int(0) which actually means SSL_ERROR_WANT_READ or SSL_ERROR_WANT_WRITE.

2) stream_select() returns write and read arrays for the async. SSL 
stream even if there's no user data (but SSL protocol data).


For a quick example, just have a look at your own code (add SSL):
guru-multiplexing.php @http://www.php.net/~wez/guru-multiplexing.tgz
(and don't forget STREAM_CLIENT_CONNECT in stream_client_connect ;-)


Maurice.
