So it rebuilds everything from scratch? All 10,000 of it?

The alternative here is, you have build 56192 checked out and built, someone 
says hey, take a look at this bug, you checkout build 49121, ./build, and 
the build system reliably rebuilds everything that has changed, and doesn't 
rebuild anything that hasn't, with the end result reliably being the same as 
the one you would have got had you rebuilt everything from scratch.

It is no coincidence that such systems tend to come out of Google.
