[Box Backup] Need to reload bbackupd conf to avoid timeouts?

OK, I'm working on it now.

No, the store will not be affected, assuming that you are running 0.10 
which already has support for keepalives on the store side (I think you 
are).

No, not strange. Box Backup caches a lot of information on the first run 
or after a reload, which requires frequent round trips to the store, 
listing the contents of each directory in turn. Once the data is cached 
(and not discarded by a reload), subsequent runs may not need to contact 
the store at all if nothing has changed, or contact it only for those 
directories which have changed.

If you back up a large data set where only a few files change between 
runs, you might see a long delay between data requests from the store, 
which might cause the SSL layer to time out. Your extended log appears to 
show this happening.

Cheers, Chris.
