8.0beta : missing umount at end of tests

[Gilles Espinasse]

Testing coreutils-8.0beta with
 -cd $(DIR_APP) && make NON_ROOT_USERNAME=nobody check-root &>
$(DIR_TEST)/$(THISAPP)-$(STAGE_ORDER).log
 # temporary during tests
 echo "dummy:x:1000:nobody" >> /etc/group
 cd $(DIR_APP) && chown -Rv nobody config.log {gnulib-tests,lib,src}/.deps
>>/dev/null
 cd $(DIR_APP) && su-tools nobody -s /bin/bash -c "make
RUN_EXPENSIVE_TESTS=yes check" \
      2>&1 >> $(DIR_TEST)/$(THISAPP)-$(STAGE_ORDER).log

Every tests are ok in 8.0beta (glibc-2.7, gcc-4.2.4, linux-2.6.27, no
selinux)
All 14 tests passed
(6 tests were not run)
All 339 tests passed
(53 tests were not run)
All 140 tests passed
(13 tests were not run)

But trying to erase source package after compilation make this error
rm: cannot remove directory
`/usr/src/coreutils-8.0/tests/cu-one-file-system.ywMta9oMdx/a/b': Device or
resource busy

Before removing sources, adding
umount $(DIR_APP)/tests/cu-one-file-system.*/a/b
fix the error

Same problem happen with 7.6
