...how nice is having tasks built-in in your preferred language, I just lan=
ded over this text (Threads =97 Threat or Menace?)

   http://www.faqs.org/docs/artu/ch07s03.html#id2923889

Just an excerpt:=20

  "Threads are a fertile source of bugs because they can too easily know to=
o much about each others' internal states. There is no automatic encapsulat=
ion, as there would be between processes with separate address spaces that =
must do explicit IPC to communicate. Thus, threaded programs suffer from no=
t just ordinary contention problems, but from entire new categories of timi=
ng-dependent bugs that are excruciatingly difficult to even reproduce, let =
alone fix."

Hmm... Why do I have this warm and cozy feeling? :-)=20

BTW, a curiosity: does the Linux version of GNAT use threads to implement t=
asks?=20
