I do not see any reason to believe there's a bug here. After the
COMMIT, CurrentResourceOwner won't be pointing at the portal's
resowner anymore, but at a resowner belonging to the newly-started
transaction (cf AtStart_ResourceOwner). The portal's resowner would
only have been used for resources that went away at commit, so it's
not needed anymore. Nor is there any code that would try to
re-install that resowner as active.
