Another way, which is safe, is to use a lock:

julia> using ChunkSplitters
       function foo(data; nchunks=Threads.nthreads())
           lk = ReentrantLock()
           iwin, datawin = nothing, nothing
           Threads.@threads for (i_range, _) in chunks(data, nchunks)
               for i in i_range
                   if !isnothing(iwin)
                       break
                   end
                   # complex computation here
                   lock(lk) do 
                       if isnothing(iwin)
                           if data[i] == 10
                               iwin, datawin = i, data[i]
                           end
                       end
                   end
               end
           end
           return iwin, datawin
       end
foo (generic function with 1 method)

julia> a = foo(test)
(29, 10)
