 * in places where we use _exit(), since _exit() skips at-exit hooks resulting
 * in lost coverage.
 *
 * To make sure we don't miss any _exit() calls, this header file is included
 * explicitly on the compiler command line via the -include directive (only
 * when built with --coverage/-Db_coverage=true)
