Probably the package upgrade should have done this for you, my fault.

I personally think so, yes, limiting the memory for long running processes (services) generally is a good idea. But finding a good default for git-daemon isn't easy, as it depends on the repositories it serves, and requires lots of memory per se. So on Debian, it's now unlimited by default.
