As I said, Frank van der Linden and I have discussed ways to fix the
softupdates memory management issues, but it involves using kernel
threads for the softupdates code (rather than doing everything from
within an interrupt context) ... probably one thread per file system.
In any case, what needs to be done is fairly straightforward, but it
will be a lot of work.
