Merge commit 'upstream/master'
Set pushed share to use default user system (id=0) instead of the first (id=1).
Do not ask for recrawl of pushed connectors. Recrawling dos not do anything, but it can take system resources to go thru them all.
Waiting for /tmp files that are locked can result in dead locks. Changed to just skipping them and then we will try the next time.
Merge pull request #9 from oiuweirwe/master
