Comment 1 for bug 1793540

3.2.1 Wed, Sep 4, 2019
 * Add support for setting timeout for convenience methods in DNS.lazy
 * Fixed DNS.req resulttype error format (LP: #1842423)
 * Use errno.EADDRINUSE instead of the hard coded Linux value for improved
   portability (LP: #1793540)
 * Update test suite to correct for use of no longer existing DNS records
 * Set timeout=1 for tests so testing with a non-responsive nameserver will
   finish in a reasonable time
