Possible memory leak with Julia-1.11.1?

[johnomotani]

I'm not sure of the cause, but I've been running into an apparent memory leak (which has crashed my laptop a couple of times due to running out of memory), when running a kinetic electron simulation on 8 cores using Julia-1.11.1. The problem does not seem to be happening with the same simulation using Julia-1.10.5, so does not seem likely to be a problem in our code.

It might be safer to stick with Julia-1.10.x for now while the new 1.11.x release series matures a bit...

I looked in to 1.11.x briefly, and what I saw suggested that we should stay with 1.10.x for now!
