Agree - I don't particularly like caching these either, given that there's
no guarantee offered (by the TS API) on the scope of these (the C plugins
typically acquire/release these handles within the same scope/hook).
Removing them altogether probably requires more effort, especially, if
there are existing plugins that rely on them and can cause compatibility
issues. I'll open a new jira (for 7.0?) to remove these completely, but, in the
mean time, re-initing at each hook seems reasonable to avoid holding to stale
references?
