Assertion in `delv` utility.

Had an assertion error for `delv` utility in trying to perform suspend 
thread.

Doesn't seem specific to any thing, argument-wise.

Environment:
Linux 4.19
Debian 10.3
Custom built Bind v9.17.1


bind9/lib/isc/app.c:422
void
isc_app_ctxsuspend(isc_appctx_t *ctx) {
	REQUIRE(VALID_APPCTX(ctx));

	REQUIRE(atomic_load(&ctx->running));

	/*
	 * Don't send the reload signal if we're shutting down.
	 */
	if (atomic_load_acquire(&ctx->shutdown_requested) == false) {


Traceback:
