When running "make check" with gcov enabled, we get the following message: hw/tmp105.gcda:cannot open data file, assuming not executed The problem happens because: * tmp105-test exits before QEMU exits, because waitpid() at qtest_quit() fails; * waitpid() fails because there's another process already waiting for the QEMU process; * The process that is already waiting for QEMU is the child created by qtest_init() to run system(); * qtest_quit() is incorrectly waiting for the QEMU PID directly instead of the child created by qtest_init(). This fixes the problem by sending SIGTERM to QEMU, but waiting for the child process created by qtest_init() (that exits immediately after QEMU exits).
