My laptop went into sleep mode, and when it came back, Emacs hung hard.
It may have changed its IP address or something.
strace showed the following:

This is a STARTTLS connection, so I'm guessing that the sendto up there
is from GnuTLS.
Assuming that my guess is correct, does anybody know whether there's
some option we can set to make GnuTLS less, er, willing to infloop while
trying to send data?
