The lio_listio interface is part of the POSIX async. I/O interface.
There's an alt-aio option now that (IIRC) uses some threads and
blocking I/O instead, and there is also the O_DIRECT option now.

Hmm, I thought PVFS used the list io interface for a long time. I

I was under the impression that PVFS has always used glibc async io,
which is somewhat outdated.
There was an attempt at a few locations to use other async io
libraries - I think we tried bullposix a few years ago - but it was
messy.

I notice now that disabling that feature is experimental. How
experimental exactly, as aio isn't really the behavior I want?
