No, only yours came via the list.

Perl is not my prefered language so I might be wrong with the
following, but I thought that sub "swap_activity" used 'qx'
to execute "$swap_activity" on the local machine.

Reading the code again I see something I ignored last time:
'qx' spawns a background process to get (and save!) these
information. At first I thought it would read them back
into 'parallel'.
