Emacs with the SpiderMonkey garbage collector

I came across this some time ago, may be of interest:<p><a href="https:&#x2F;&#x2F;github.com&#x2F;Wilfred&#x2F;remacs" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;Wilfred&#x2F;remacs</a><p>It&#x27;s a port of the EmacsOS to Rust, should be able to run all your elisp code at some point.

<i>The main difference between the current mark-and-sweep garbage collector and the SpiderMonkey garbage collector is that the latter is a copying garbage collector and precise, meaning that objects may change address during GC and that only typed values, not memory locations that might or might not be, must be trace</i><p>Out of all the types of gc out there going to a copying gc seems not very compelling. Mark and sweep is not bad at all (well understood, straight forward to implement), and you don&#x27;t have to worry about double dereferencing pointers (ie some implementations of Cheneys, I don&#x27;t know if spidermonkey refercences are indirect pointers to one of two buffers).

Could someone explain, for someone not familiar with low level programming, what would be the advantages of using another garbage collector in Emacs?

my emacs gc strategy: disable the gc. do manual collections by restarting every now and then.

Wow! My gut instinct would have been to try Boehm, but I have no idea why one would prefer one GC over another with Emacs.
