Do you know code paths you see tasklist_lock being hot?
I am looking at some of the exec/signal/ptrace code paths because they get subtle corner case wrong like a threaded exec deadlocking when straced.
If the performance problems are in the same neighbourhood I might be able to fix those problems while I am in the code.
