gevent 1.0b2 is available

[Denis Bilenko]

New beta release of gevent is available at http://code.google.com/p/gevent/downloads/list

Major and backward-incompatible changes:

- Made the threadpool-based resolver the default. To enable the ares-based resolver, set GEVENT_RESOLVER=ares env var.
- Added support for child watchers (not available on Windows).
  - Libev loop now reaps all children by default.
  - If NOCHILD flag is passed to the loop, child watchers and child reaping are disabled.
- Renamed gevent.coros to gevent.lock. The gevent.coros is still available but deprecated.
- Added 'stat' watchers to loop.
- The setup.py now recognizes gevent_embed env var. When set to "no", bundled c-ares and libev are ignored.
- Added optional 'ref' argument to sleep(). When ref=false, the watchers created by sleep() do not hold gevent.run() from exiting.
- ThreadPool now calls Hub.handle_error for exceptions in worker threads.
- ThreadPool got new method: apply_e.
- Added new extension module gevent._util and moved gevent.core.set_exc_info function there.
- Added new extension module gevent._semaphore. It contains Semaphore class which is imported by gevent.lock as gevent.lock.Semaphore. Providing Semaphore in extension module ensures that trace function set with settrace will not be called during __exit__. Thanks to Ralf Schmitt.
- It is now possible to kill or pre-spawn threads in ThreadPool by setting its 'size' property.

I just noticed that the code still uses include_dirs=["libev"]. So, at
the moment people should delete the libev and/or c-ares directories in
order to not embed them. I'll fix that now.

What's the rationale behind choosing threadpool-based resolver as
default?

Well, while c-ares-based resolver works fine for me on a Linux
machine, it seems that it sometimes produces surprising results for
others. I believe on Windows the situation with c-ares resolver is
even worse.

Thus it occurred to me that the threadpool-based is probably a better
default choice. However, if I'm wrong, we can always switch it back
before the final release.
