[Bug ports/4353] New: interfaces going away crashes sudo with SIGABRT in ifaddr stuff

["kduda at arastra dot com" <sourceware-bugzilla at sourceware dot org>]

If you run "sudo true" over and over, while in the background you create and
delete tap interfaces as fast as you can, sudo will crash about 30% of the time
with SIGABRT.  This is on a Linux-x86-fc6 system, glibc 2.5-10.fc6.  I assume it
is crashing somewhere in sysdeps/unix/sysv/linux/ifaddrs.c but it is a little
hard to tell because I can't convince sudo (being setuid) to leave a core file.

Sorry this isn't really very well isolated and the reproduction path isn't
really that specific.
