OK, I have been able to reproduce this to some extent.  I'm using
'curl -o /dev/null http://www.google.com' which times in at about
1.5 to 2 seconds with 'tty' and about .5 seconds without.  I don't
have any additional data at this point but I thought I'd "chime in"
with a "me too", since I know that's what this list is all about. ;-)
Actually, I wanted to let Brian and any others know that this
doesn't appear to be specific to their configuration.  If I find out
more, I'll report back.
