In my case several threads use this single address permanently.
What do you think of this:
We do a for-loop over the address chain in Curl_connecthost() in
connect.c (CVS-revision 1.130: line 789)
Alternatively I could count the number of addresses, choose the
starting address, jump to the head after reaching the tail and terminate
the loop when reaching the starting address again.
Unless a certain option is set the starting address will be the head itself.

looking forward to you comments
