Usually such large sort_area_size is used for batch processes, so there is
no problem with many such jobs running at the same time. It can be done
befor e running the job and then back to old value after the job ended. Also
if hash_area_size parameter default value is sort_area_size.
This is why the job which took 60 hours finished in 30 min. in previous
message and not because sorting became faster.

Mininmal disadvantages besides overextending the
machine's memory...eg if 100 people are all doing a
large sort at the SAME time, you could have 100 x 10m
of memory or more getting munch up...But the memory is
only used when they want to do a sort ...
