and, of course, there are libAsync and fpAsync as wrappers for 
select()... (libAsync is purely procedural, while fpAsync uses classes)
As select() can be quite painful in more complex situations, fpAsync 
will hide most of this complexity, and adds more functionality (e.g. 
powerful timers). In the future it will be available on more platforms 
than Linux/Unix.
Both are part of the FPC packages.
