A guest handler that called exit threw out of the libc exit path because the exiting thread waited on itself. Like FreeBSD, the nested call now runs the handlers that are still registered and ends the process with the status it passed.
The relinker's repeatable --executable converts another executable of the
title beside the output, sharing its libs, app0 and guest modules.
sceSystemServiceLoadExec maps /app0 paths to those executables, passes the
argument list on the new command line and finds the main executable through
APS5_EBOOT. RetroArch (PPSA99169) starts its frontend picker this way.

On Windows std::_Exit ends in ExitProcess, which still runs every module's
DLL_PROCESS_DETACH and TLS callbacks after the other threads are gone. A
static destructor that joins a worker then waits forever: a title that calls
_Exit while libSceVideoOut's flip queue runs (ps5-opengl's retirement
fail-stop) stays alive in FlipQueue's destructor. _Exit and libkernel's _exit
now terminate the process with TerminateProcess, as _exit ends a POSIX
process: no atexit handlers, stream flushes or module destructors.
