run() not capturing exitcode properly?

[Gabor Szabo]

> my $p = run "ls", "dadsad", :out, :err;
Proc.new(in => IO::Pipe, out => IO::Pipe.new(:path(""),:chomp), err =>
IO::Pipe.new(:path(""),:chomp), exitcode => 0, signal => 0, command =>
["ls", "dadsad", "adadsa"])
>
> $p.exitcode
0


While for the same command in the shell   $? will hold 1 as the
directory does not exist.

Is this a bug or am I misunderstanding something?

This is Rakudo version 2017.04.3 built on MoarVM version 2017.04-53-g66c6dda
implementing Perl 6.c.

Running on OSX.
