the "status" column of toolforge build list currently has three possible values, "ok", "error" and "cancelled". The implication of this is that builds that are still running are also reported as "ok" but this can be confusing for a user.
Imagine running a build (that will eventually fail) and the status is reported as "ok" along side builds that has completed and are successful.
A typical user will go ahead to try and make use of the build image because the status was "ok".

We should have a fourth value like "running" or "pending"
