Hello,

With 2013-10-10-alpha there was a behavior change in ksh which causes shell to block \
in below example :

      1 #!/bin/ksh
      2 function zzz
      3 {
      4 sleep 30 >/dev/null &
      5 echo $!
      6 }
      7 
      8 PID=$(zzz)
      9 echo "PID=$PID"

This regression is caused by parameter change from '1' to '3' at [1] and has not been \
fixed in upstream yet. Is anyone aware about fix for this issue ?
