Correction: in formats where we scale the number of key slots based on
actual thread count, the actual memory usage on most systems will be
substantially less.  It's just the when those arrays are in .bss,
they're pre-allocated for the maximum supported key slot count, even if
a lot fewer slots are used with typical thread counts.  With dynamic
allocation, we'd be able to allocate memory for fewer key slots.
