I have a feeling there's a bug with ht->nelems, since the crash is
always in the grow worker, but I haven't quite put my finger on it
yet.

Can you show me a stack trace?

Oops, just deleted the old ones to reproduce with some debug printks :)

It's always while trying to grow a table from the worker; it kills
processes, but eventually no process are left and the kernel panics.

I'll send you a trace when I have one again - I'm running a new
reproduction now.
