I think infinity is the right solution:
The only common case where infinity is wrong would be Android - and 
Android disables sysv shm entirely.

There are two patches:
http://marc.info/?l=linux-kernel&m=139730332306185&q=raw
http://marc.info/?l=linux-kernel&m=139727299800644&q=raw

Could you apply one of them?
I wrote the first one, thus I'm biased which one is better.
