Well, long story short: the build script compares the two .buildinfo
just after the build and if Build-Environment differes it re-runs the
build a 3rd time.
If that fields differs again (this might be the case for very long
running builds that spawn several dinstall and different toolchain
packages change during the day) it just gives up and mark the package as
unreproducible

Agree, be assured discussing some stuff on IRC is really quicker than
email.  Though when it comes to #debian-reproducible following
everything might be sometimes annoying due to the volume of the chats,
but imho is still worthwhile :)
