inotify to minimize stat() calls

Hi,

For large repositories, many simple git commands like `git status`
take a while to respond.  I understand that this is because of large
number of stat() calls to figure out which files were changed.  I
overheard that Mercurial wants to solve this problem using itnotify,
but the idea bothers me because it's not portable.  Will Git ever
consider using inotify on Linux?  What is the downside?
