It is believed to be reasonably high for non-upload use cases, and
reasonably low to prevent DoS by uploading large files (with
default 1 worker processes and 512 worker connections it's possible to
consume up to 512M in client_body_temp directory).

For upload use cases one is probably going to tune it for his own
limits anyway - taking into account available disk space and so on.
