The code in qemu_init_child_watch() wasn't clearing the 'struct sigaction' before passing it to sigaction(); this meant that we would block a random set of signals while executing the SIGCHLD handler. Initialize properly by using memset() on the struct, as we do in similar cases elsewhere. Signed-off-by: Peter Maydell <peter.maydell@linaro.org> Signed-off-by: Michael Tokarev <mjt@tls.msk.ru>
