Correct but now there is no better way to implement parallelism. I
know some
languages have new syntax for it which is actually exciting. Maybe
some day
FPC will support such syntax but that is future. Now is now.

Well...
IMHO the whole threading model is basically flawed, but currently there
is no other alternative. At least not in any language I know.

Programming threads is error-prone, and needs careful design of your
classes. I doubt that the lazarus IDE is very thread-safe, and
therefor I
think that the lazarus devels do not enable threading by default.

This is also why the UseCThreads is there. There is no need to drag in
thread support if you don't use it: it creates additional dependencies
which you simply don't need if you don't program using threads.

Yes but now I want to use it. I don't care if other parts of the IDE are
"thread-safe". My thread is running only when the user is reading one
settings
dialog and it is done in a safe way. It simply makes the program better.

What would you suggest? How to commit the code so that we don't get
complaints
about RunErrors?

This is a question the lazarus devels must answer. I just provided a
possible hypothesis why currently they don't use it :-)

In my experience, if you don't need them don't use them just for the fun of it. This makes coding and debugging way easier.

In case of lazarus, what do you want to do in a thread ?
