Describe the problem
Occasional error: concurrent map iteration and map write when updating all outdated libraries with IDE2 (from this build: arduino/arduino-ide#2281).

I see that the board discovery (board list -w) stopped/started for each lib installation in IDE2. It’s a good question why, and I found this five times in the logs. Maybe it’s unrelated:
2023-12-06T16:34:52.820Z daemon INFO time="2023-12-06T17:34:52+01:00" level=warning msg="Error loading library" error="rpc error: code = Internal desc = loading library from /home/xxx/Work/Sketchbook/hardware/arduino-git/esp32/libraries/I2S: invalid library: no header files found"
To reproduce
It's probably a race condition. Therefore, there is no clear way to reproduce it. Try updating all outdated libraries in IDE2.
Expected behavior
There is no concurrency error when installing libraries with the CLI daemon.
Arduino CLI version
arduino-cli version 0.35.0-rc.7
Operating system
N/A
Operating system version
n/a
Additional context
Maybe related: #1828.
Related in IDE2: arduino/arduino-ide#1389.
It's causing a daemon process crash in IDE2, and the app becomes non-functional.
Issue checklist
- I searched for previous reports in the issue tracker
- I verified the problem still occurs when using the nightly build
- My report contains all necessary details
