DBCC INDEXDEFRAG causing blocking

I am using DBCC INDEXDEFRAG to defragment indexes. According to BOL
DBCC INDEXDEFRAG "does not hold locks long term and thus will not
block running queries or updates." But several SPIDs are blocked by
the INDEXDEFRAG SPID. The blocked SPIDs have a waitresource of TAB:
5:436352769 [] (436352769 is the table whose index I am defragmenting)
and waittype of LCK_M_IS. These SPIDs are being blocked for a long
time (30+ minutes).
Any help would be appreciated.
This is on SQL Server 2000, sp4
Thanks!Known 'feature', with hotfix available.
