Hi,

I'm doing a research on how to allow arbiter clients to map bar regions
into their spaces. It seems to me the approach should be:

1.- Make the arbiter implement paging
2.- Expect clients to mmap() the region files the arbiter generates

Sounds that correct for you?

I'm a bit confused with libpager, the reference manual seems to be obsolete:

https://www.gnu.org/software/hurd/doc/hurd_5.html#SEC32

From this document I assumed I should create a pager for each region
file, call page_demuxer from the arbiter's demuxer and implement
callback functions. But it seems pager_demuxer() is not defined anymore
and servers use pager_start_workers() which I'm not sure what's for.

Is there more recent documentation about libpager?
