---help---
Clean-up can either mean packing files together toward the end of
the file or, if files are deleted at the end of the file, clean up
can simply mean erasing the end of FLASH memory so that it can be
re-used again. However, doing this can also harm the life of the
FLASH part because it can mean that the tail end of the FLASH is
re-used too often. This threshold determines if/when it is worth
erased the tail end of FLASH and making it available for re-use
(and possible over-wear). Default: 8192.
