While searching for another problem, I noticed a set of lines like the
following for each table in my database's schemas (including the SYS*
ones). What did I do (?) or what did DB2 see to cause this? It caused a
perceptible slow down in response time while it was going on.

ADM9501W  BEGIN online index reorganization on table "IS3     .OWNERS" (ID
"108") and table space "USERSPACE1" (ID "2").
