>Description:
when main thread and son threads call accept() after bind() at the same
time , main thread's accept() will return -1 yet son threads's return 
value is ok.
(env: g++ 2.95, pthread ,all are origin installed version)
same programs tested in redhat linux 7.1 and aix4.3 , and all return 
correct value after accept().
>How-To-Repeat:
example:
void (*fun)(..) ;
main(){
 ...
 int s = socket (...) ; 
 bind(...) ;
 pthread_create(fun,...) ;
 int v = accept(s,....) ; // here will always return -1 . 
 ...
}

void* fun(s){
 ...
 int sv = accept(s,...) ;  // return ok
 ...
}
>Fix:
this is used for thread pool server mode . don't let main() call accept() when thread pool call accept() .
