Clearing hanged builds

[Matt McGill]

I've got a build that has hung, leaving Continuum to permanently  
display "In Progress..." for its status. I read in a previous message  
to this list that it was somehow possible in 1.0.2 to clear the  
offending build out of the database without doing it manually, but  
I'm unsure of how to do so. Can someone clue me in?
