Linux processes hang on crash (not exiting)

[limbonaut]

On Linux, crashed games don't exit fully after crash leaving the process hanging perpetually in limbo state.
This happens due to multiple crash handlers registered, one in our extension and the second one in Godot Engine.

More on crash handler conflicts.

• PR in Godot Expose OS.disable_crash_handler() for extensions godotengine/godot#108268
• Investigate how to turn off Godot crash handler #229

Workaround: Launch your game with --disable-crash-handler option.
