Ever since I've been running v6.12.34, I've noticed that from time to time, when BOINC downloads new tasks, it will immediately preempt an existing task and switch to one of the new tasks immediately, rather than waiting for the existing task to checkpoint.

Is this a bug in the scheduler, or is there some good reason for throwing away the work that has been done since the last checkpoint on the task that is preempted?

I'm sure that this didn't happen on v6.10.x or earlier versions.

I've just seen this happen with v7.0.28 too.
