It seems that hudson "sometimes" puts the wrong build-number in the environment.
I developed a small maven plugin which writes build-number, build-id and
revision to a properties file. Sometimes however, the build-number in the
environment differs from the actual hudson-build number. The difference can be
up to 3 builds. After some time, the build-numbers are synchronous again.

I don't know how to reproduce this issue, it may correlates with the "Hudson
building jobs twice"-bug which I am also experiencing.

Hudson-Version: 0.123
Project-Type: Maven2
Container: Tomcat 5.5
OS: Linux (Debian Etch)
