Modified files:
sys/kern kern_sig.c
Log:
In kern_sigtimedwait, remove waitset bits for td_sigmask before
sleeping, so in do_tdsignal, we no longer need to test td_waitset.
now td_waitset is only used to give a thread higher priority when
delivering signal to multithreads process.
This also fixes a bug:
when a thread in sigwait states was suspended and later resumed
by SIGCONT, it can no longer receive signals belong to waitset.
