OK, moved my response there. For those who haven't seen my original
posting, it's at http://curl.haxx.se/mail/archive-2004-07/0088.html

This is interesting. Just building libcurl with c-ares did not change
much, but then I increased the timeouts. Before they were connect:5
secs, full xfer: 10 secs. When increasing them to 30 and 60 secs
respectively, all of the transfers succeed.

(I also tried NOT using c-ares, but just having the longer timeouts.
This does NOT work - I get lots of timeouts. Quite odd).

BUT: The times are much longer than what I see when using the simple
interface - orders of magnitude, in fact. With the simple interface,
fetching a URL takes a fraction of a second; using the multi-interface
both the connect and the total time are 5, 10 or even 20 seconds.
For comparison, see the log file at
