I don't think speed is really worth worrying about. The remote query will
take orders of magnitude more time than the possibly-useless context
creation.
The code is really designed to put all the setup for storeRow into one
place; but I concur with Joe that having teardown in a different place
from setup isn't very nice.
An alternative that might be worth thinking about is putting both the
context creation and deletion at the outermost level where the storeInfo
struct is defined. That seems possibly a shade less surprising than
having it at the intermediate level.
