object for further manipulation.

Unlike the C<new> method, this method I<always> spawns a new perl process
(except in some cases, see L<AnyEvent::Fork::Early> for details). This
reduces the amount of memory sharing that is possible, and is also slower.

You should use C<new> whenever possible, except when having a template
process around is unacceptable.

The path to the perl interpreter is divined using various methods - first
C<$^X> is investigated to see if the path ends with something that looks
as if it were the perl interpreter. Failing this, the module falls back to
using C<$Config::Config{perlpath}>.

The path to perl can also be overridden by setting the global variable
C<$AnyEvent::Fork::PERL> - it's value will be used for all subsequent
invocations.

        Unlike the "new" method, this method *always* spawns a new perl
