In the past few days, I've hit hangs a bunch of times in various places - 
more than I've ever seen before, but I am doing more complicated things 
recently compared to before (which was running a few relatively trivial 
jobs in a bunch of relatively trivial workflows).

Its an awkward user experience. In some cases, the code should perhaps 
detect such hangs; and in other cases, perhaps different logging info in 
the -debug output would be useful...
