yes,  one would expect that.  :)  But  I'm not so sure I trust 2.4.0
as much as 2.3.x at this point.   2.4.0 has had some major changes and
is still undergoing changes, some of which may not be heavily tested

In this specific case,  the change was made on September 4th, and the
svn comment says "improved code by eliminating code duplication" -
this was the only change to this file for this particular commit. So
the change to close_conn() in the 2.4 branch does not appear to be in
an attempt to fix a bug or make the code more correct, it is an
attempt to remove some duplicate code, but in fact it could introduce
a bug considering that it looks like close_conn() won't do anything in
this case.
