It looks like because before the second time running of
WhichDBTestCase.test_whichdb(), previous dumb files are not cleaned clearly, so
the gdbm's open() doesn't create a new gdbm database but open an existing dumb
database.
In fact during the working of #9523, I found this problem and fix it in the
patch of #9523. Here I extract the fixing, it is simple:
cat patches/issue10228.diff
