Partially so it seems. However, my testing with Process Monitor (from
sysinterals) shows that most of the access denied errors occur when
removing directories.
The blind rename-remove dance doesn't work when removing entire
directory trees as now the renamed file/directory might be held
pending delete when the removing parent directory.

For testing, I used regrtest -F -j6 test_import
Without patching it would fail consistently (albeit randomly).
