CICS has begun using the term "threadsafe" to describe programs that can
run "simultaneously" (i.e., on different TCBs and on different CPUs
within the same CEC at the same time) with update intent to shared (or
shareable) resources without compromising the integrity of those
resources. Perhaps "single-thread[ed|ing]" vs. "multi-thread[ed|ing]"
might serve your purpose?
