Yes this feature is widely used.

Considering that none of SHM_HUGE* has been exported to the userspace
headers all the users would have to use the this flag by the value and I
am quite skeptical that application actually do that. Could you point me
to some projects that use this?

Hmm Andrew, if there's not one example, could you please pick up this patch?

Thanks,
