crypto: data race in SecureContext::AddRootCerts?

[bnoordhuis]

Possible data race when worker_threads are active?

node/src/crypto/crypto_context.cc

Lines 749 to 751 in 1287530

	if (root_cert_store == nullptr) {
	root_cert_store = NewRootCertStore();
	}

root_cert_store is a static X509_STORE* that is assigned to (and read from) without any kind of synchronization, AFAICT.
