Maybe I'm seeing ghosts, and I don't even have a minimal clue about what goes on in the code, but this looks fishy:
Plenty of ghosts in qcow2, of all those explorers who tried to brave the code. Only Kevin has ever come back.
preallocate() invokes qcow2_alloc_cluster_offset() passing&meta, a stack variable. It seems that qcow2_alloc_cluster_offset() may insert this structure into cluster_allocs and leave it there. So we corrupt the queue as soon as preallocate() returns, no?
We invoke run_dependent_requests() which should dequeue those &meta again (I think).
