ok, but then we should do it right.

1. the error and warning exceptions (class.t3lib_error_warning.php, 
class.t3lib_error_error.php) should be actually used by the php 
error_handler (like it is done in Flow3 trunk)

2. instead of filling up t3lib/ with exception classes we should either 
create a subdir "exception" (like it is done in t3lib/cache/). Or we 
should collect them at a central point. e.g. in the error/ directory.

3. we should provide some examples in the core for usind the specialiced 
exceptions, e.g. by replacing the die() calls in t3lib_db by proper 
t3lib_db_exceptions (-> follow-up).

Dmitry and Ernesto, if we agree on this I'll prepare a new patch.
