I forgot to mention about -lthr (1:1 KSE threading) related problems.
1. If the program is compiled with '-static -lthr', the program
crashes at the first thread creation. Stack trace follows.
(gdb) bt full

2. Without -static, the program works fine, but pthread_create()
fails with EAGAIN at thread count 110. B.T.W. pthread_create() return
value handling was wrong in the example program. It always confuses
me. :-( How can I increase this limit? Again, I'm looking for
something like ten thousands.
