That's what I was thinking....it doesn't really hurt anything.

We actually have a remote_fileopen command in our protocol.  The host sends
an open command to the target and then just sends blocks of data for the
target server to write out.  Then a close message tells the remote to close
it.  It's basically identical to an ordinary open command so you can open on
the remote for reading/writing/etc.

I'm not sure about gdbserver though.  Do you even presume the existence of a
filesystem on the remote?
