I have no idea whether this is relevant, but I see port 25, which is
SMTP.  The implementation of SMTP is synchronous in Zope 3, AFAICT.  I
found last week that sending out emails through a very slow SMTP server
tied up Zope 3's server threads waiting for that server's response,
which led to in turn to Zope 3 being nonresponsive.
