Lingering pluggable_discovery.py processes on GNU/Linux

[dos1]

For the past two days I have used arduino-cli to program an ESP8266 board while having RP2040 core installed. This resulted in many instances of RP2040's pluggable_discovery.py lingering on my system.

Calling arduino-cli board list or any other command that triggers pluggable discovery process creates a new one and they never go away unless killed manually.

I still have this problem on Arch running 4.4.1 and arduino-cli 1.1.1.

Me too.
Working with other boards instead of Pico/RP2040, process Pytyhon3 for pluggable_discovery.py run out the CPU, I can hardly to anything.

• Windows 10
• Arduino 1.8.13
• arduino-pico 4.4.1

Walkaround: I renamed pluggable_discovery.py to prevent it excuting, or turn off Arduino-CLI in VSCode Arduino settings.
