Unfortunately, some of them don't survive the next job because they
have the same name for every job until tilesGen is restarted and gets
a new PID.

I am planning to work on that because I wanted to prepare the client
for the "download while rendering" feature Spaetz requested.

In the mean time I was so annoyed by the lack of a decent exception
handling in Perl that I was almost ready to re-implement the whole
thing in Python (which would also have the potential advantage that
some code could be shared between the server and the client).

But, after that I found the Error module on CPAN which implements this
and I want to give it a try if nobody objects.

This will add the dependency on this module (in Debian called
liberror-perl) to the client.  So the client will only survive the
automatic update if this module is installed.
