For asynchronously provided sessions, the parent has to maintain the session state as long as the server hasn't explicitly responded to a close request. For this reason, the lifetime of such session states is bound to the server, not the client. When the server responds to a close request, the session state gets freed. The 'session_response' implementation does not immediately destroy the session state but delegates the destruction to a client-side callback, which thereby also notifies the client. However, the code did not consider the case where the client has completely vanished at session-response time. In this case, we need to drop the session state immediately. Fixes #2391
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.
