In this case I had an error at the very beginning, and the frontend
was just frozen, without any messages having been emmitted by the
kernel yet.  Kind of staring at a blank wall...

But I figured it out by the sheer power of my raw intellect (aka,  I
stared at the same line of code for 5 minutes until I realized how
dumb I was).  All good now :)
