Yeah this is an "undocumented feature". Don't really understand why,
because unlike the Unixish
system( 'program params &')
this is actually portable.
The only place I found this documented are the perlport and
perl56delta and perl561delta manpages. But it is being used in
IPC::Open3, Shell.pm, IO::Pipe and PPM::Installer::Local.pm.
