Best way to pass arguments to an Apache2::SubProcess?

So my will has crumbled, mostly because I'm probably not very good at 
the "resident in memory" part of mod_perl and I will be using 
Apache2::SubProcess to fire off a sub-process.

There seems to be two easy ways to send data to my detached sub-process; 
via an \@args or via $r->subprocess_env->set.

I would like to pass large data structures which I will JSON encode and 
I'm wondering which of the above would be best for that, if any, and 
what the limitations are of either.

Also, I was wondering, in the docs for Apache2::SubProcess in the 
section about properly detaching the sub-process it has in the example:

$r->spawn_proc_prog ('/path/to/detach_script.pl', $args);

Is there a reason $args is used rather than \@args as outlined earlier 
in the docs?

opt arg2: \@argv ( ARRAY ref )

Or is it possible to create an $args->[0..10] and pass that?

Thanks!
