Our output is simply redirected to a file. This file is later parsed  
and committed to the database in one go using another program (well,  
actually it's uploaded to www.freepascal.org, where a program does  
this parsing and committing).

The main cause of slowness when running the fpc test suite is the  
thousands of compiler, assembler, linker and test program invocations  
(assembler and linker only on platforms without an internal assembler  
and/or linker, obviously).
