BTW, I just confirmed through careful reading of the Tcl exec man page
that: "If any of the commands writes to its standard error file and
that standard error is not redirected and -ignorestderr is not
specified, then exec will return an error; the error message will
include the pipeline's standard output, followed by messages about
abnormal terminations (if any), followed by the standard error

So standard error always follows standard output for Tcl exec. It's
not interleaved.
