| - From /etc/dhclient.conf (for ISC dhclient):
| 
| prepend domain-name-servers 127.0.0.1;
| 
| This results in for me in:
| 
| search sandelman.ottawa.on.ca
| nameserver 127.0.0.1
| nameserver 192.139.46.30
| nameserver 207.176.162.14
| nameserver 66.11.170.98
| nameserver 192.139.46.1
| nameserver 192.139.46.33
| 
| so, I still get to try what the DHCP server told me, in the event that my
| local DNS can't cope.

As I understand it, this will multiply the resolver's timeout by a
factor of 6: one for each entry.  Supporting evidence, from
resolver(5):

	If there are multiple servers, the resolver library queries them in
	the order listed.

It also has the effect of generating an even more tangled set of
holds.  And each time you try a query, you exercise a different path
so you may get a different behaviour, making it harder to debug.

This seems like a very bad idea.  Why not fix your local DNS?
