Post saving failing because of slow Twitter OAuth

Hello,

while our post saving has worked, it resulted in a white screen instead of taking us back to post editing.

Here is the entry from PHP slow log:

I checked inc-cl/apis/tmhOAuth.php and see:

        'curl_connecttimeout'        => 30,
        'curl_timeout'               => 10,

I adjusted curl_connecttimeout down to 10 seconds.

It seems it was waiting close to full 40 seconds allowed as the post was saved, but then it just showed a white screen.

Using cron is not a solution for us as we need our post to be on Twitter immediately. If it fails to be posted right away, then it needs to be scheduled with a Cron. Does it work that way?

Thanks!
