[LAD] jack_showtime out to QProcess

Jack_showtime man page doesn't mention any options available and
the problem I have is the frequency of the lines it outputs.
Over 12,000 lines per second according to a little Perl script.
($ jack_showtime | perl -w line-counter.pl)
I can get to see relevant lines in my program, but it seems
to need all of this (j_s is the jack_showtime QProcess):
j_s->readAll(); // otherwise old news
waitAbit(20); // otherwise blank line
QString dirout = j_s->readLine(); // "
dirout = j_s->readLine(); // A recent relevant line
ui->statusbar->showMessage(dirout, 0); // show it.
Has to be a better way. A jack_showtime option to limit its
verbosity to n lines per second, would be the nicest, if anyone
is around that way, but for now; maybe a script could tame it?
Any suggestions appreciated.
Thanks again, John.
