data pump parallel slave killed, other slaves pick up the work?

Oracle 18c, RAC

impdp ... parallel=...

If I kill one of the parallel slave sessions (alter system kill session...), will the work assigned to it be picked up by the other sessions? RMAN is designed this way. How about data pump?

In case you ask why I need to know:

We're hitting a bug described in

Library Cache Lock' (Cycle) Seen During DataPump Import in 12.2 RAC Environment (Doc ID 2407491.1)

If we run impdp in serial mode to avoid this bug, it takes almost 3 times as long. If we set _lm_share_lock_opt instead, the whole database must be bounced, not one instance at a time. (Some parameters such as db_files require the same value across all RAC instances. If it's a static param, it's very annoying.) At our shop, unless it's extremely critical, we never bring down a production database once it goes into production.

Howdy, Stranger!
