Perl's gethostbyaddr doesn't seem to have this problem
as shown
below.  Should I report this in the bug tracker?
 
$ time perl -MSocket -lwe 'print +(gethostbyaddr
inet_aton("datavortex.net"), AF_INET)[0]'
datavortex.net
 
real    0m0.063s
user    0m0.050s
sys     0m0.010s
 
$ time python2 -c 'from socket import * ; print
gethostbyaddr("datavortex.net")[0]'
datavortex.net
 
real    0m20.176s
user    0m0.070s
sys     0m0.020s

This smells like a local configuration bug on your system, on my system it works fine (0.220u 0.110s 0:01.85 17.8%     0+0k 84+10io 0pf+0w). Look in your /etc/resolv.conf (or similar file for your platform) to see that there aren't any non-existing hosts listed there.

Although, of course, that doesn't explain why perl has no delay...
