Just like you assumed:

Destroying /dev/serial/by-id/usb-Arduino__www.arduino.cc__Arduino_Mega

I will try to implement your suggestions. Though it could take a while with my perl knowledge :)

Is it somehow possible to declare the $arduino object as shared, so the garba collection avoids it?
This 
my $arduino : shared;

[download]
does not work.

So the idea is to create a new Device::SerialPort class which inherits the original class and overrides the destructor, right?
