Ah, now I remember. It seems that sometimes when SSL_ERROR_WANT_READ was returned, things would block; that is, the "handle_read" method on asyncore.dispatcher was never called again, so the SSLSocket.recv() method was never re-called. There are several levels of buffering going on, and I never figured out just why that was. This (very rare) re-call of "read" is to handle that.
You certainly do need to call read again if OpenSSL fails an SSL_read with a want-read error, but in asyncore, you don't want to do it right away, you want to wait until the socket becomes readable again, otherwise you *do* block waiting for bytes from the network. See the SSL support in Twisted for an example of the correct way to handle this.
