Other than that I agree with Junio, from what we've seen so far, Lustre
returns EINTR on all sorts of calls that simply aren't allowed to do so.

I don't think this analysis is 100% accurate, POSIX allows error codes
to be generated other than those defined. From
http://pubs.opengroup.org/onlinepubs/009695399/functions/xsh_chap02_03.html:

"Implementations may support additional errors not included in this
list, *may generate errors included in this list under circumstances
other than those described here*, or may contain extensions or
limitations that prevent some errors from occurring."

So I don't think Lustre violates POSIX by erroring with errno=EINTR,
but I also think guarding every single function call for EINTR just to
be safe to be insane :)

However, looking at Eric's log, I can't see that being what has
happened here - grepping it for EINTR does not produce a single match.
