 While I haven't run official timing tests yet, this is definitely a big
 improvement!

 As for my edge case... ultimately I'm planning to profile the low-level
 TCL code related to thread management: My hope is that there might be
 something that can be done to speed things up, particularly for older
 macOS releases.

 But since this is only an issue for my specific development use-case - and
 I'm also in the process of migrating to Sequoia [via OpecCore] - this
 won't be a big deal in the long run.

 Still, I'd like to keep this open for now, to track the profiling effort.
