[ale] file system trigger

[Jerry Z. Yu]

The reason they don't want cron is probably they want instaneous access to
the uploaded files. Then again, on a powerful box, you can run your batch
really  frequently.

I guess you can tailing the xferlog or ftp.log. when you seem something
gets uploaded ('STOR blah' has 226 status and some size), then send some
predefined SIG to that sleeper apps. or just call that post-upload app
directly.

Or, hack the ftpd source, to set up a post-upload/download
directive|feature.
