Right, theoretically something bad could happen here (though not
likely). Here's a fix. Sorry for attaching with something so trivial,
but Thunderbird isn't very cooperative..

Signal notifications.

delivered only through queue, otherwise both delivery types are
poll/select() notifications.
This patch includes generic poll/select notifications.
kevent_poll works simialr to epoll and has the same issues (callback
is invoked not from internal state machine of the caller, but through
process awake, a lot of allocations and so on).

* [oh, everybody will hate me for saying this, but...] to me, kevent
implies an internal kernel subsystem. I would rather call it uevent
or anything else lacking a 'k' prefix.
* I like the absolute timespec (and use of timespec itself)
* more on naming: I think kevent_open

Hi Evgeniy,
I have used kobject_uevent() to notify userspace about some events.
For instance, when memory comsumption reaches a predefined watermark,
a signal is sent to userspace to allow applications to free resources.
But I am not sure if kobject_uevent() is the more appropriate way for
that

the easy case where the headroom is known exactly beforehand.
