pgbench does not get to "assume that threads are available", at least
not as long as the project as a whole supports --disable-thread-safety.

As I said, I wouldn't have a problem with restricting the --jobs setting
on threadless platforms, which seems like it would fix your problem since
you wouldn't need to have more than one process involved.
