"no exception handler available" when using async task in script

[tkf]

InterruptException can be caught in "simple" script (like sleep.jl below) provided that it's started using include (julia sleep.jl does not work: #25308). However, including @async in the script makes it impossible to catch InterruptException:

$ cat sleep.jl
try
    println("sleeping")
    sleep(10)
catch err
    @show err
finally
    println("done")
end

$ julia --startup-file=no -e 'include("sleep.jl")'
sleeping
^Cerr = InterruptException()
done
julia --startup-file=no -e 'include("sleep.jl")'  0.61s user 0.66s system 67% cpu 1.877 total

$ cat async.jl
@async println("Hello!")

try
    println("Hit ctrl-c!")
    sleep(10)
catch err
    @show err
finally
    println("done")
end

$ julia --startup-file=no -e 'include("async.jl")'
Hit ctrl-c!
Hello!
