Sometimes very long to delete a project

[laurent-alfonsi-linaro]

It is sometimes, very long to delete a project, and if too long, finally it doesn't succeed to delete it.

It seems to happen when there's many build results in the project.

For instance, I haven't been able to delete thee projects [1] and [2]

Thanks
