You could just abort the task before freeing it.

With GNAT (maybe just with older versions, maybe not on all
platforms), if you free a task before it has terminated it will
silently not do the deallocation. The trick is to loop until
'Terminated is True.

I had to create a scavenger task; tasks that had been aborted were
placed on a queue for the scavenger task to free when the task had
terminated. Fairly gruesome generics involved.
