Alternatively, you can immediately release any individual autoreleased object by doing

[[someObject retain] release];

(The -retain increments the reference count, removing it from the autorelease pool, then the -release triggers the deallocation of the object.)

When an object gets deallocated, is it then set to nil? In the above sample, is then "someObject" == nil? Or does that variable contain an invalid (unallocated) memory address, as would a similar pointer that has been free'd in POC (plain ol' C)?
