julia> pmap((x)->error("error"), [1])
exception on 1: ERROR: error
 in error at error.jl:21
 in anonymous at none:1
 in anonymous at multi.jl:601
 in run_work_thunk at multi.jl:563
 in remotecall_fetch at multi.jl:635

 in anonymous at multi.jl:1366

At this point, Julia hangs, and no amount of ^C mashing seems to do anything. I've tried setting err_retry=false, err_stop=true and I get the same behavior. This happens regardless of whether or not there are worker processes.
