I don't know how it's implemented, but my first bad experience with tmpfs /tmp was discovering that Vagrant wrote machine images there, and everything started behaving super poorly. Is it safe to use now with large files?

tmpfs is totally usable with large files - as long as you have enough RAM to spare and don't have it go to swap.

I use tmpfs continuously on server VMs, with multi GB files and/or up to 80 GB in smaller files (precomputed mysql tables...) - always worked without any issues. However, these VMs don't have any swap configured (or even swap support in the kernel), so YMMV.
