Any plans to add limitations of filesystem to the call like maximum file

rather than trying to write 4 GiB and then file, it would be good to at some

Adding filesystem limits can be done.  I got a shopping list of things people
wanted a while back and I've worked off of that list.  I can add other things
- that's on of the reasons I left room for expansion.
