Is it possible to install inotify extension on normal mercurial? Is it extension, or patch?

[Marcin Kasperski]

Considering 'inotify extension' is *extension*, it seemed to me 
that I can download it, install, and use against normal 
(distro-installed) mercurial. But 
http://www.selenic.com/mercurial/wiki/index.cgi/InotifyExtension
leads to
http://hg.kublai.com/mercurial/patches/inotify/summary
which contains different patches against mercurial sources.

So, is it possible to use inotify as extension, without compiling 
mercurial?
