What exactly does this mean? you are creating a table in the database, or
creating a table object in the application.

"Freeing the table" suggests you're talking about a table object, i.e.
TIBOTable. Were you aware that a table object hides a SELECT * query with
no WHERE clause? If it's on a big table, and you free the object before
the query has finished fetching (the normal state a table object is in)
then the destructor has to wait until the fetching is all done before it
can commit the transaction and proceed to destroy itself. So whatever
comes next in your code won't happen until that stuff is all finished.

Sure, until next time you run that same code; then you'll have another
"frozen" instance.
