[Catalyst] Test server problem

[Will Hawes]

If I run the test server with -r, it fails to restart whenever I modify 
a CDBI class. This is irrespective of whether the modification itself 
breaks the class - it can be something as benign as adding a comment.

When I modify files elsewhere in the app, the restart does happen.

The message displayed in the debug output is a rather cryptic:

File "C:\Documents and Settings\Will\My 
Documents\pondwood\trunk\lib\PondwoodDB\
Entity.pm" modified, not restarting
