I'll admit that I'm not actually very interested in the problem you're 
solving, I've never hit that problem so I'll leave it for those who have 
to comment on the idea and implementation.

But I'll comment on the email: for some reason, the implementation you 
give has extraneous pipes | at the start and end of each line, e.g.:


|class ReloadingHandler(StreamHandler):|
|    """|
|    A stream handler which reloads the stream object from one place if an error occurs|
|    """|

Between the extraneous pipes and the lines being line-wrapped, the code 
has ended up severely mangled.

(Code being emailed probably needs to stay below 78 characters per line 
to avoid being wrapped at the ends of lines.)
