Hmm... okay.  Yes, maybe.  I don't know.

That was stupid of me anyway, because it's quite obvious
from the source code that `process-send-string' is only
defined in one place.  (Maybe that's even true for built-in
functions in general.)

To me, this seems like a bug in Emacs, because I don't think
it should be possible to trick it into giving an invalid
argument to some file operation.

This is what the relevant code looks like:

   rv = emacs_write (outfd, (char *) buf, this);
   [...]
   if (rv < 0)
   [...]
     report_file_error ("writing to process", Fcons (proc, Qnil));

So apparently one of `outfd', `buf' and `this' is invalid in
that call to `emacs_write'.

You get that error every time you try to pause, right?
