Release Name: 2.0.0
Notes:
sleepy_penguin 2.0.0
sleepy_penguin provides access to newer, Linux-only system calls to wait
on events from traditionally non-I/O sources. Bindings to the eventfd,
timerfd, inotify, signalfd and epoll interfaces are provided.

* sleepy.penguin@librelist.com
* git://bogomips.org/sleepy_penguin.git
Changes:
There are many internal cleanups, bugfixes, and incompatible
API changes. The API will probably be stable from now on.
All the flag passing is less verbose, in the past you had
to do:
tfd = TimerFD.new(TimerFD::CLOEXEC|TimerFD::NONBLOCK)
Now, you can just do (the old way still works):
tfd = TimerFD.new([:CLOEXEC, :NONBLOCK])
A SignalFD interface now exists, but is not recommended since
MRI signal handling seems to conflict with it.
Inotify#close no longer holds the GVL while closing the
descriptor since it is an expensive operation.
See git log v1.4.0..v2.0.0 for all the gory details.

close(2) on inotify descriptors takes forever and a day.

Author: Eric Wong
Date: Thu Mar 10 03:28:48 2011 +0000
inotify: add Inotify#each method for yielding each event
This is useful for processing events in a synchronous fashion,
we think...

Author: Eric Wong
Date: Thu Mar 10 02:12:46 2011 +0000
eventfd: remove "_nonblock" interfaces
Instead, allow a nonblock flag to be passed to

interfaces.

Inotify#take releases GVL unconditionally
Avoids using select(2) if we want blocking functionality on
Ruby 1.9.

doc: improve RDoc documentation

interfaces, too :)

signalfd: test with sigqueue() with DL help
Still doesn't work under 1.8, oh well :<
commit 32bc376e494b5477b921b6d198b7aeda0c8efe12
Author: Eric Wong
Date: Thu Mar 10 02:12:46 2011 +0000
rework flags passing for ease-of-use
Arguments now take symbols and arrays of symbols just like the
SignalFD.new method. This fixes some use of signed vs unsigned
integer conversions as well.

Author: Eric Wong
Date: Thu Mar 10 02:12:46 2011 +0000

disable epoll optimizations test if Strace::me is missing
Better than failing.

Author: Eric Wong
Date: Sun Mar 6 01:01:46 2011 +0000
remove TimerFD.create, it's redundant
Even though it matches timerfd_create(), TimerFD.new is
more consistent with the rest of the library.

Author: Eric Wong

inotify: use StringValueCStr for paths
This will fail on '\0' bytes since it's an illegal path
character.

Author: Eric Wong
Date: Sat Mar 5 23:34:53 2011 +0000
