Ops, you are correct, it is a one shot event:

I think I implemented it as a repetitive event. ops =D I guess I'll
need to fix this.

But you should not try to compare directly the LCL gtk2 or qt4
widgetsets with fpgui since gtk2 and qt4 do most of the real work.
Lazarus now has a X11 interface which can be used for direct
comparisons and it uses the timeout. In general I don't fully trust
select() to wakeup correctly yet. I guess that more testing would show
if it does, but I read in the web that X11 could use more then one
file descriptor for communication, so if I use a infinite select() the
application could hang in some corner cases.
