Yes, I had but pretty much got the same output as the buildbot slave.
But I just tried --traceback and it's definitely complaining about the
connection being terminated.

Regular test:

> hg clone --verbose --noupdate http://hg.python.org/cpython test
    real URL is https://hg.python.org/cpython
    requesting all changes
    adding changesets
    adding manifests
    transaction abort!
    rollback completed
    abort: connection ended unexpectedly

Traceback:

    requesting all changes
    adding changesets

I also stuck on --debug which generates a metric ton of output, but
the final portion is:

> hg clone --debug --traceback --verbose --noupdate http://hg.python.org/cpython test

which appears to die mid-stream while receiving the manifests.

So I'm sort of hoping there might be some record server-side as to why
things are falling apart mid-way.
