True. My next guess is it's using the index because your WHERE clause is
Rushmore optimized. So it still doesn't need to move the record pointer in the
source table. And I'll return to how your environment is setup. I'd have to go
read the fine docs to understand why moving the record pointer is also trying
to lock the row. Do you have SET MULTILOCKS ON?

Leaving aside the environment stuff like SET EXCLUSIVE and SET MULTILOCKS, my
first guess is COUNT FOR actually moves the record pointer through every row
in the table, Whereas SELECT COUNT() is reading the header.

Why would a COUNT FOR hang ("Attempting to lock") whereas my easy workaround is
SELECT COUNT(*) FROM SomeCursor WHERE <<yada yada yada>> ??
