in reply to Re^2: Two processes of a Perl EXE
in thread Two processes of a Perl EXE

Here, I found the following that seems to be included in the module docs:

When a non-dependant PAR package runs, there is a two stage binary frontend: first the executable demo.exe that I ran, then a second demo.exe that is extracted to the temp dir and run as a child of the first. If you look at the process list while demo.exe runs, you'll see two processes with the same name.
