Is it a bug in gpg (oddly, the kernel reports lots of entropy available,
and generating the signatures themselves is quite fast)? Or is the new
version doing something special in the import process that we need to
work around or disable?

Answering my own question (somewhat): this is bisectable in the gnupg
repository, and it turns out to be caused by their 4473db1ef (agent:
Kludge to mitigate blocking calls in Libgcrypt., 2016-11-11), which
introduces a 100ms sleep (yuck) that is presumably triggering way more
than it needs to. More details at:

So this does seem like a gpg bug.

I've submitted a bug report to gpg:

  https://bugs.gnupg.org/gnupg/issue2897

so we'll see what they say.
