> hmmm... I wonder if it would be simpler to make QD_MEMORY_STATS
non-configurable? IOW, get rid of the flag and just always provide memory
statistics. It's pretty obvious we haven't tested QD_MEMORY_STATS=OFF as part
of our CI.

> Just an opinion, thoughts?
I am all for getting rid of the flag once and for all and always provide
memory statistics but first I want to understand why this flag was introduced
in the first place ?
If we decide to keep this flag, we need to augment CI (preferably GHA) to
test with QD_MEMORY_STATS=OFF. That will add *yet another* build type to the
already long list of tests we run, so I am inclined to say let's just get rid
of this flag.
@ted-ross what do you think ?
