They don't provide Perfect Forwarding Secrecy, so they don't need
cryptographically strong random numbers. I think using PFS is a
mistake in this context (because it's too costly, as you've noted),
but the last time this has come up on debian-devel, the consensus was
that PFS is important to warrant this inconvenience.
