No more waiting on drain

On startup, pspy ignores inotify events for 1 sec since it creates lot of them itself (Draining file system events due to startup...). Many people experienced much longer waits though on some systems. This release should fix that.

Improved troubleshooting

Small update: pspy will now print the version when it starts up. It will also kill itself if unrecoverable inotify errors are discovered rather than running indefinitely.

Improved reliability

A few small changes:

• Fixing errno 22 errors: I suspect the errors mentioned in issue #3 are due to passing a small buffer to the read syscall. inotify events can be huge if the path to the files are large. The buffer is now much bigger and there should be no more errors.
• Changing colors: since probably nobody uses file system events (used to be green) too much, we now have different colors for different UIDs in process events and no colors for file system events.
• Adding a --debug flag. By default it is false and error messages are suppressed. Since errors can be excessive for some machines and are not really interesting I think it is a good default.

Initial release

First official version of pspy.
