Kse/Thr _exit implementation

[Kai Mosebach]

Hi again,

i have two other questions regarding the kse/thr implementation:

1.) often i see, that the linuxthreads implematation has problems with
the
exit() function, if not all threads are finished. Is this fixed in kse ?

2.) i found this piece of code in the sapdb, which had to be enabled,
when i used linuxthreads, but with kse it just loops around, so i
removed it. Is this problem described here lthreads only ?

cheers

references are
     * situated on the pthread stack, freeing this stack results in

actually was terminating
     * solves part of this problem. Creating another dummy thread solves
the synchronization.
