It's related to Cross Instance Call,
For instance, when you drop (truncated) a table Oracle has to flush this table's buffers out from the Buffer Cache, so it issues a cross instance call.
These calls are used even if you're not using OPS.

Would anyone know off hand what a CI type lock is?

This is from the output of the following query: select ksqsttyp eq_type,
ksqstget gets,
ksqstwat waits
from x$ksqst
where ksqstget !=0
/

On Oracle 7.3.4.4.0
