SVN rev 184216 on 2008-10-24 01:03:31Z by davidxu
partly revert revision 184199, because TDF_NEEDSIGCHK is persitent
when thread is in kernel mode, it can cause dead loop, now unlock
process lock after acquired sleep queue lock and thread lock to
avoid the problem. This means TDF_NEEDSIGCHK and TDF_NEEDSUSPCHK must
be set with process lock and thread lock being hold at same time.
