BTW, this has bitten us in various other cases, we should fix it once
and for all in the C code by marking the process as "busy" while we're
running the filters so we never run filters recursively.
[ If we ever bump into a case where recursive filters are needed, we
  can then add some function to remove the "busy" mark.
  Calling (accept-process-output PROC) should naturally mark PROC as
  not-busy.  ]
