As I recall, you're on a 32-bit machine, right? If so, a limitation
you may run into is simply running out of address space. If it's not
an address space issue, we don't need to mmap anything; you could just
try enabling swap, and use the existing e2fsck code.
(I had assumed you had tried that before suggesting you use the
scratch_files tdb approach....)
