I'm seeing this on build 73. My steps to reproduce are:
(in xterm)
1) ksh93
2) clear
Trussing ksh93 indeed shows it receiving a SIGCLD indicating
its child was stopped with a SIGTTOU:
Received signal #18, SIGCLD [caught]
siginfo: SIGCLD CLD_STOPPED pid=1825 status=0x001B
Received signal #18, SIGCLD [caught]
siginfo: SIGCLD CLD_CONTINUED pid=1825 status=0x0019
Instead of just:
Received signal #18, SIGCLD [caught]
siginfo: SIGCLD CLD_EXITED pid=1830 status=0x0000
which I get when I run some other command under ksh93 that writes to
the terminal or when I run clear under ksh88.
Curiously, both 'clear' and 'tput clear' are sent SIGTTOU, though
'tput clear' doesn't reproduce the problem.
Additionally, trussing ksh93 with -f causes the problem to go away.
Smells like a race to me.
