You can save directly by sending "write filename.txt" to the
subpatch-receiver (like [write file(---[s pd-data]) and read back in
with a "read file" message.

The funny thing is, that running such a 18MB patch is no problem,
however opening it again after saving is a problem. Hopefully this can
be sorted out sometime.
