My recommendation is never unload a library once loaded.
I don't see the point, unloading and reloading on demand
risks crashes and memory leaks. Others may disagree, but
I prefer to not assume that unloading is safe.
In OpenSSL 1.1.0, we try to do our best to make it safe,
but some one-time static allocations will still leak and
crash safety is likely platform-specific.
