Most systems that support such a model - and yes, they're still being
both developed and used - are well enough written to avoid a single
global lock.

This is the model used by the Linux kernel, among others. You might
argue that one of Linus's repositories is a "master" copy, as that's
the one that Linux kernel releases are cut from, but that's really the
only thing that distinguishes it from any of the others. Each
developer gets to decide where they want to take patches from and
which patches they're actually going to use in any given build, but
most can't put code in the so-called "master" repository.

I'd say a project with 14 million LOC and thousands of developers
using it for five years demonstrates that it's both workable and
scalable.
