RE: a question about tst-cancel2

thanks for your reply.  :)

yeah, pthread_testcancel() is a point to execute cancel buffer
code. But in tst-cancel2, there is no place to call 
pthread_testcancel().  :(  So there must be another place 
to call __do_cancel(). 

I have checked all places to call __do_cancel(), 
init.c::sigcancel_handler()
_pthread_cleanup_pop_restore()
pthread_testcancel()
pthread_enable_asynccancel()
pthread_enable_asynccancel_2()
__libc_enable_asynccancel()
pthread_exit()
pthread_setcancelstate()
pthread_setcanceltype()

but I failed to find the tst-cancel2 to run one of them. :( 

any pointers? thanks.
