> When I run a simple query "select count(1) from lineitem;" in one tsql session and after
that run the 2nd query in another tsql session.  The 2nd one hung.  
> After the 1st one done,  the 2nd one still stuck at 0%.
> After that, run the same query in the first tsql session, the 3rd query also hung.
