Possibility to alter task payload while handling it.

[michatw]

Hey!

I'm wondering if there is a possibility to alter the payload of a task once it is queued.
I'm searching for a way to store the progress of a task while handling it, so that when my program crashes and the current task gets pushed back to the queue the task's payload contains some information about what part of the task has already been done. If this works I could check the payload when handling the task again and can proceed processing at the point it has been before the programm crashed.

Any ideas? I'm grateful for any help!
