Hi,

        While starting up Gnus, the NSM presented me with a
        dialog to accept a certicate.  I pressed "s" for
        "Session only" but noyhing happened: the prompt to
        "Continue connectinh?" remained in the echo area.

        I starced" the Emacs process and saw that it was in a
        tight loop printing:

recvmsg(6, {msg_namelen=0}, 0)          = -1 EAGAIN (Resource temporarily unavai
lable)

        several times a second.

        "C-g" woulf not abort nor allow me to interact with the
        Emacs process.

        Here's some GDB info, if it helps.

        Thanks.
