do you have other event handlers handling exe event data too? do they return
ECORE_CALLBACK_PASS_ON? here is some basic sample c code that also throws in
handlers for add and del of the exe too and print exit code. I see line
buffered data in multiple events. it takes 5 events to deliver all of the
output. i used /bin/ps to ensure my aliases don't change anything from my user
shell env. i returned ECORE_CALLBACK_PASS_ON to pass the event on to other
event handlers of the same type of event. i set up handlers before i run
anything to ensure they are in place first... ?
