Description
When master Julia process is waiting in take!() on its own RemoteRef and the worker processes have all thrown exceptions, pressing Ctrl-C in REPL results in
ERROR (unhandled task failure): InterruptException:
in task_done_hook at ./task.jl:175
but doesn't bring the master from the waiting state.

Research direction
Start by reproducing the REPL scenario where the master waits in take!() on its RemoteRef after all workers throw exceptions. Read task_done_hook at ./task.jl:175 and trace how Ctrl-C is handled while the master is waiting; done means Ctrl-C returns the master from that state without the unhandled task failure.
