The following code will recurse until Python throws an
exception:
"""
import email.Utils
addrlist = ["foo@bar.com"] * 2000
email.Utils.getaddresses(addrlist)
"""

I found a huge address list in my spam archive, which
is how I found the error.  Attaching suggested patch
that avoids recursion.

bugfix candidate I guess?

Funny, I just copied the implementation of this up from
rfc822.py into _parseaddr.py and it has something very
similar to what you done.  It uses += instead of .extend()
but I think that makes no difference.
