1. Some of the fpga tools are closed-source so I can't check with
confidence that they will never try to use mmap.
Or even more confusing, it may use mmap() in a way that is irrelevant to what filesystem it or the data lives on.
2. The go compiler is open-source so it was a simple matter to make
an experimental variant on linux which uses read/write instead of
mmap (as it does on plan 9). I still get the bus error code=0x2
when running this over v9fs. Hence the remaining v9fs problem is
not mmap related.
Well, good luck getting it all going!
