I don't believe that rename() should lead to removal of file disk blocks
(at least with a rename() on the same file-system, which seems to be all
that POSIX requires be supported (see, e.g., the description of the
EXDEV error case... though I do think it's ambiguous) and all RTEMS
allows at present), since it's just changing the file name that links to
that data.
You can use rename() to delete files.
