strange behavior of 'rm'

[Mikus Grinbergs]

I experiment with manually adding/deleting Activities, then restarting
Sugar.  Sometimes I've seen obsolete activity-versions being listed in
some sort of snapshot recorded in shell.log.  I've empirically found
that I can lessen this by deleting ~/.sugar/default/favorite_activities
- and letting the Sugar restart rebuild that file.

A couple of times I've found that the 'rm' command I issue for this
purpose (e.g., from Terminal, while running as root) appears not to
work.  [The latest occurred on os353pyg - I don't remember which earlier
builds I saw it happen on.]  I'm mystified:

> 0 [~]# rm .sugar/default/favorite_activities
> rm: remove regular file `.sugar/default/favorite_activities'? y
> 0 [~]# rm .sugar/default/favorite_activities
> rm: remove regular file `.sugar/default/favorite_activities'? y
> 0 [~]# rm .sugar/default/favorite_activities
> rm: remove regular file `.sugar/default/favorite_activities'? y
> 0 [~]# ls -la .sugar/default/
> total 21
