I just use 2.3 :-) You can probably fix your problem with out of memory
during file-in by inserting a few Smalltalk garbageCollect (or whatever
the method name is) in appropriate places in the file you are filing in. 
That way it will do a garbage collect and give you more free memory /
objects for the rest of the file-in.  It seems that garbage collection
isn't as automatic as we users wish it is during file-in and other
times. 

By the way, if you creat a huge object in 2.5 and then dereference it,
you will find that you have more free memory after dereferencing it than
before creating it.  I susupect that PP 2.5 only allocates memory from
the Mac OS as it needs it.
