I have not put any attention on making the autoprewarm parallel. But
as per the current state of the code, making the subworkers to load
the blocks in parallel should be possible and I think could be easily
added. Probably we need a configurable parameter to restrict max
number of parallel prewarm sub-workers. Since I have not thought much
about this I might not be aware of all of the difficulties around it.
