How can I set a maximum limit for gzip module?

[t.nishiyori]

Hi tokers,

I understand gzip-module that if buffers reach the limit, the module will
wait some buffers are free. 
I think there is a new question the resource (such like cpu and memory) will
be over, when upstream contents are large size and lots of traffic.
I cannot set the limit of size of upstream contents. Because my nginx proxy
is handling a lot of traffic from a third party. 

My nginx server which turn off the gzip-module was so fine in almost two
years. So I think there is no problem, but I am a little scared.
If I encounter this problem unfortunately, please ask you such like "Why
dose't gzip-module have a max_length directive" again.

Thank you so much.
