This has been discussed here before.  I haven't searched the 
archives and don't remember the details, but I think the PDSE 
space reclamation happens when the dataset is closed, not as 
soon as the member is deleted or replaced.  This close does not
take place for a dataset in the linklist of ultiple MVSs.

I could very well have the explanation wrong, and it may be woefully
out of data (as I said, this was over 4 years ago) but at the time
this was "working as designed" behavior.
