Wow.....we gotta fix what is wrong with colleges today.

Blocking is irrelivant.  The concept of a record integrated into the
OS kernel is mandatory.  You don't lock a block...unless your MS
trying to market your single user Access data file system as a multi-
user database.

See prevoius message about lock manager, distributed lock manager,
distributed transaction manager, and clustering.
