Not sure if its the case in PLD but in TLD apache init script doesn't 
wait for all processes to stop (and these scripts were same at some 
point, didn't checked if they're same now).

This happens when some process is busy when receiving kill signal, ie. 
handling page which is doing some large database query and it will not 
quit immediately. It also will always happen when some apache process 
has hung. I'm not seeing this behavior more than few times per year and 
in my case its almost always related to database queries.

Perhaps we should add some checks to wait for all apache processes to 
quit in similar way we do in squid init script?
