I don't think that it has a problem with lacking the right int64
format specifiers. However, I had a bad feeling about integer overflow
of state->currentRun, and think I'll need to address that. After all,
if runs are now no longer 2x work_mem on average, it's not completely
ridiculous to imagine that being an issue on a misconfigured system.
