I don't think this is correct; the certificate issuer must come from
certain well-known CAs which allow upgrading to a better security
level. If you don't need interoperability with crippled clients,
you'd use RSA instead of RSA_EXPORT in the first place.

But on a typical GNU/Linux system, no periodic tasks read from
/dev/random, so it doesn't matter if the pool has been depleted or
not. And the process which generates the key parameters for Exim
would not block, either.
