Thanks - the problem is kind of pressing for me since it is giving
me some problems keeping up with the number of websites I monitor,
but I knew about your summer-holidays.

I'll be willing to try and troubleshoot it as best I can myself, but
I have very little idea about how the flow of control is inside
libcurl. From my limited debugging, it seems that the timeout's
trigger in the connect.c::Curl_is_connected() routine:

  if(has_passed > allow ) {
    /* time-out, bail out, go home */
    failf(data, "Connection time-out after %ld ms", has_passed);

but why this happens I haven't been able to find out. All of the
time values look right - it really does take more than my timeout
setting before the timeout triggers - but why doesn't curl notice
that many of the connect() calls actually do succeed ?
