As long as the following causes no problems (from the SunOS 4.0
ABORT(3), but it comes from the S5 documentation and reflects S5's
implementation as well):

   NAME
        abort - generate a fault

	...

   DESCRIPTION
        abort() first closes all open files if possible...

"Open files" here refers not just to file descriptors but to standard
I/O streams; i.e., buffered output will be flushed.  This could cause
that buffered output to be printed twice, if it gets flushed later in
the parent as well.
