522830dea8 Revert "waitpid() can block if it takes a long time before the child terminates" 
This reverts commit bfba5c7249eff8a10a43b53c1b89dd44b625fd10.

revert the waitpid changes.   we need to waitpid for some childredn so should
refactor the approach completely

d67de4a7d2 waitpid() can block if it takes a long time before the child terminates 
so we should not call it from the main daemon.

1, set SIGCHLD to SIG_DFL to make sure we ignore this signal

2, get rid of all waitpid() calls

3, change reporting of event script status code from _exit()/waitpid()   to write()/read() one byte across the pipe.
