Garbage collection is always done on a block-by-block basis. The need to run
gc is checked on almost every writing operation (write(), close(),
open(),...). At present this is done by checking various gc thresholds.
Instead, or in addition, we could also get the gc to run until there is no
more garbage. Perhaps this could be done in a background thread so that the
gc can grind while the fs is not busy.
I guess this could also be ttriggered by an ioctl() or similar too.
