Sounds like there's a bad leak.

We don't have a memory profiler: (profiler-start 'mem) simply uses
memory allocation as an approximation of time, but your problem is
likely not due to memory allocation but a lack of memory reclamation
(i.e. a leak).

Returning memory to the OS can happen sometimes depending on lots of
different details, but it's basically irrelevant to your problem: If
there's a good reason why it got to 6GB, then returning to a smaller
size is good, but not indispensable.  In your particular situation, IIUC
Emacs should simply not have gotten to 6GB in the first place.

Yes, please,
