if i connect to a remote system using pfsockopen, and the remote system closes the connection (say it's a web server, and returns 500), subsequent calls to pfsockopen (to same remotes system) return a stream resource, but attempting to use the resource results in "invalid stream" errors.

seems like it's returning the original connection, even though it's not alive, instead of creating a new one.

this is in a single script (so a single process), and is repeatable.

i reproduced in isapi and cgi under IIS/W2K.
