FWIW, I checked my Emacs instance – uptime 3 days, 21 hours – and I have
112.8MB private memory, 196.6 total (including OS toolkit memory returnable
to the OS) on macOS.  So, while I'm uncertain what our comparative load is,
I'm definitely not seeing similar numbers on a build from last Thursday.
This is on macOS, but past experience says that platform is more likely,
not less, to show excessive memory use.

I'm assuming that this is almost all private memory (that is, a leak, as
Eli says) but
https://raw.githubusercontent.com/pixelb/ps_mem/master/ps_mem.py will print
a useful summary and confirm that.
