This prevents the memory with glibc allocator from sticking around and just results in address space fragmentation until you close the given alacritty window.

I'm not sure how good idea that is, but it seems to kind of solve #5438 .

This issue is also less noticeable with the default mimalloc settings.

The main issue with this thing is that it's relatively slow when you have a lot of junk and it's likely not a great way to solve this, but it really seems that we're just fighting the allocator.

probably the better option is to figure out what exactly breaks the ability of glibc allocator to release everything back.

Draft because I have no idea whether it's a good solution for that...
