- We want to always use time_set_timew, as timew is 64-bit even on 32-bit
platforms so we need to be careful to both write that size, but still
trigger write barriers if we end up with a heap object. -
-
-
- We are inserting directly into the st_table, so we need to issue a write
barrier from the hash. -
- This object was newly allocated on move_enter, so some GC may happen and
it may have been marked by move_leave, so we need to issue an

10:51 PM Revision 3cfd71e7 (git): Fix minor typos in comments, specs, and docs
- Just a bit of minor cleanup
Signed-off-by: Tim Smith <tsmith84@gmail.com> -
- This write barrier occurred before the entry was added to the table, so
if GC occurred when inserting into the table, the write could be missed. -
- After returning from the callback in st_update is the point that the
hash table may be resized, which could trigger a GC and mark the table
being used for the tally.

- 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). -
