D'oh! Serves me right for just skimming the release notes, then. After
doing some in-depth reading, this is a problem for the Linux community
at large. Wow. While I'm glad the kernel's getting choosier about where
and how to harvest entropy and can personally live with the ~30 seconds
added to VM boot times, it could be painful to, for example, bootstrap
a Linux guest on AWS for the first time and wait for the initial SSH
keys to be created.

Will be interesting to see how this evolves over time. In the meantime,
as this is not actually a kernel defect, I suppose this bug can be
closed.
