Well, not exactly none, but a limited env

My revised keeper:
How to run and release a file:
Note: this command runs OUTSIDE the shell. There are no
environmental variables to be found such as $HOME
the parameters are in quotes, including the name of
the program to run, just like `run`
$ p6 'my $pA = Proc::Async.new( "/usr/bin/leafpad" ); my $promise =
$pA.start; await $promise;'
$ p6 'my $pA = Proc::Async.new( "/usr/bin/leafpad" ); $pA.start;'
$ p6 'my $pA = Proc::Async.new( '/usr/bin/leafpad
"/home/linuxutil/XferParts.pl6.tmp"' ); $pA.start;'
To get this to run with the shell, call "bash -c".
Note: all the parameters to the command bash executing
with "-c" go into an embedded quote stream.
For example:
'/usr/bin/leafpad "/home/linuxutil/XferParts.pl6.tmp"'
my $pA = Proc::Async.new( "bash", "-c", '/usr/bin/leafpad
"/home/linuxutil/XferParts.pl6.tmp"' );
say $pA;
$pA.start;
Proc::Async.new(path => "bash", args => ["-c", "/usr/bin/leafpad
\"/home/linuxutil/XferParts.pl6.tmp\""], command => ("bash", "-c",
"/usr/bin/leafpad \"/home/linuxutil/XferParts.pl6.tmp\""), w => Any,
enc => "utf8", translate-nl => Bool::True, win-verbatim-args =>
Bool::False, started => Bool::False)
