The GNU libc doc for BUFSIZ says "Actually, you can get an even better
value to use for the buffer size by means of the fstat system call: it
is found in the st_blksize field of the file attributes."
And `stat --help` says:
...
Valid format sequences for file systems:
...
%s block size (for faster transfers)
So maybe:
io.popen('stat -f / -c %s')
