Note that it is unclear if the PRE syscall for rt_sigsuspend is properly setting up a temporary mask in the thread state tmp_sig_mask: if an handler is called while a thread is calling sigsuspend, the mask during the handler run must be the temporary mask set by sigsuspend. It is not clear if/where the valgrind sigframe builder/handler sets the tmp_sig_mask to the value as expected by the user (i.e. the value of the temporary mask which was given to the sigsuspend syscall) git-svn-id: svn://svn.valgrind.org/valgrind/trunk@16141
