That seems to be the consensus, so I'll go make it happen.

I think the way forward is to do what we had as of HEAD (984c92074),
but add the ability to transmit the blacklist table to parallel
workers. Since we expect the blacklist table would be empty most of
the time, this should be close to no overhead in practice. I concur
that the idea of marking the relevant functions parallel-restricted is
probably not as safe a fix as I originally thought, and it's not a
very desirable restriction even if it did fix the problem.
