[sword-devel] Downloads exceeding 45 seconds are timed out?

[Troy A. Griffitts]

We need to push 1.7.0 out the door. I'm about to roll back the 45 second 
timeout unless someone can tell me what they think the libcurl setting 
should be and we can get it in and test it immediately.  If we roll back 
the timeout setting, if one of our repos goes down and a frontend tries 
to refresh all repositories, then the frontend will look like it is 
stuck refreshing.  I believe it took like 2 minutes to stop trying the 
connection in the past.  I would really like to set a connection 
timeout, but I'm not a libcurl expert and obviously what I thought was 
the correct setting is not, if the download stops after 45 seconds.  
Does anyone have the time to track this down?  If not, we've had this 
problem in previous releases, so we'll need to roll it back and keep our 
repos online so we don't run into a problem.

Please consider taking the time to track this one down.
