Using this reg_cache is racy across ractors, so don't use it when in a ractor. Also, its use across ractors can cause a regular expression created in 1 ractor to be used in another ractor (an isolation bug).

Using this `reg_cache` is racy across ractors, so don't use it when in a
ractor. Also, its use across ractors can cause a regular expression created
in 1 ractor to be used in another ractor (an isolation bug).
