If you can't know anything about the future of UST, and you have a single
CPU system, how can UST timestamps EVER match?

Unless I misunderstand what you're saying, you can only ever get UST by
asking what is the UST *RIGHT NOW*.  Two plugins or two threads doing this
can never, by definition, run at the same time on a single processor.  Maybe
you can context switch or change to a new plugin before UST changes, but
that is haphazard at best.  And if UST is based on the cycle clock, you're
guaranteed to NEVER get the same UST twice.

So what am I misunderstanding?
