Have a look at logger frameworks.

LazLogger is included: http://wiki.lazarus.freepascal.org/LazLogger
Use "debugln" instead of "writeln". debugln will test if stdout is open 
or not.

There are still cases where stdout can return a "disk full", those are 
(in the latest version) caught and ignored.
