One can even explore the memmap machinery and see if we can
entirely drop the temp-file and use the system paging for that:
so if the input exceeds the maxinput, we just mmap /dev/zero file
I believe something like that should be possible but will have to
double-check if this is true.
I knew it ("man mmap" on solaris):
When MAP_ANON is set in flags, and fd is set to -1, mmap()
provides a direct path to return anonymous pages to the
caller. This operation is equivalent to passing mmap() an
open file descriptor on /dev/zero with MAP_ANON elided from
the flags argument.
I'd have to see if this is really working on Linux, Mac and Win.
