Alexander, what was the original application which you
were working with where you encountered this thread stack problem?
It would be good if multithreaded code that was written 
on Linux or Solaris worked as much as possible "out of the box",
especially large applications like GNOME.  Like it or not,
these are dominant platforms, and we might have to adjust
a bit to accomodate their quirks of large default thread stack size
(a developer can always decrease the stack size with
pthread_attr_setstacksize() if his application requires a smaller stack).

What is the patch that would be required to increase the
default stacksize in libpthread, so that mainstream
applicatons like GNOME, or the application you were working
with, would "just work"?

Is it something like:
