Hmm, some more data.
It seems that the newest snapshot improves things a little; it fails an
indeterminate number of times until it succeeds (I've seen 1,5,7 failures),
and then succeeds thereafter.
Even stranger was that I went back to the old dll, and was getting the same
behavior. But the last three times I could not get a connection after *many*
tries.
For the record, if I restart sshd after adding the user, things work again.
If I then delete the foo user, it fails to work again.
