Just picking a nit. The #cvs.lock directory exists for the duration or a write lock or the time it takes to create a new read lock file. read lock files exist for the duration of a read-only operation.

If your problem is excessive swapping, then decreasing this would cause processes to wake and be swapped in more frequently.
