-drain was introduced with GC, where -release was optimised away in either the 
compiler or the runtime and never delivered.  It allowed the GC implementation 
to use autorelease pools as a hint that there were a lot of short-lived objects 
to delete and have the same code work in non-GC mode.  ARC fixed this a lot 
better by introducing the @autoreleasepool syntax, and should be used in all 
new code.
