The signal_1/2/3 objects (which are threads) are in destruction, but still signals are send to them. When the signal arrive and the memory for the signal_1/2/3 object is already invalid we operate on stale memory and all the locking infrastructure of the Thread don't work anymore. Be more robust, explicitly wait for the termination of the thread. Issue #2284
This is the example operating system based on the Genode OS framework: :_Init_: is the first real process in the system. The provided implementation uses a very simple XML parser to read its configuration files. :_Drivers_: The example OS has basic drivers for frame buffer, mouse and keyboard input, the PCI bus, the real-time clock, and system-specific timers. :_Server_: The only server in the example OS is Nitpicker, a minimal-complexity GUI server. :_Test_: are also part of the example OS. You may have a look at the fork bomb as a simple system stress test. :_Ldso_: is the dynamic linker used for loading executables that are linked against shared libraries. :_Lib_: contains libraries used by the components of the OS repository, for example, the alarm framework.
