I very much doubt that you can measure any difference at all between
these two codings of the function.

I agree with the principle you mention, of not holding resources for
long if they can be released earlier; but in this case the table_close
call occurs across a ReleaseSysCache() call, which is hardly of
significance.  It's not like you have to wait for some other
transaction, or wait for I/O, or anything like that that would make it
measurable.
