Cough. Can't resist... Could you also explain why
http://marc.info/?l=linux-nfs&m=133252084301205 can't work?

To clarify, I am just curious, I am not arguing. I am asking because
if UMH_WAIT_PROC(timeout) fails with -ETIMEDOUT, then perhaps it makes
sense to not "leak" the user-space process servicing the kernel request
we were waiting for.

Oleg.
