Microsoft has confirmed that this is a problem in the Microsoft products that are listed at the beginning of this article.
This fix introduces a change in functionality for SQL Server trace flag 1118 on SQL Server 7.0 only. When you
turn on trace flag 1118, all allocations for tables in the tempdb database will allocate full extents to the table. However,
allocations for small tables (less than 8 pages) in other databases will continue to allocate single pages
from "mixed" extents exactly as they would if the trace flag were not turned on. The behavior of
SQL Server trace flag 1118 on SQL Server 2000 remains unchanged. If SQL Server trace flag 1118
is enabled on SQL Server 2000, mixed extent allocations are disabled in all databases.
SQL Server trace flag 1118 is used to reduce allocation contention in tempdb.
