Hm, you're right. That must be the reason why I never used it ;-).

But you're right, just after I sent my mail I was thinking the same
(what would happen if someone else did a "pre-tested commit" (or just
a regular commit) at around the same time as my "remote build" is
running?). I guess TeamCity would just start my "remote build" with
the latest sources it has (checked out from version control (which
should be updated after every commit) at the time.

OTOH, the same problem would probably come up if you'd try to do this
in a pre-commit hook (unless someone decides to synchronize those
pre-commit-hook-builds, but wow, then it would be even more blocking
:)). And the same problem is also there if you ask your developers to
perform a private local build and set of unit tests before they

If I were to use this feature in my organisation, I guess I would
handle this pragmatically: there should still be an automatic
build+tests running on TeamCity (or whatever continuous build system)
running builds after every commit. This can catch any problems with
concurrent-commits after the fact ...
