	sys/kern       : sysv_msg.c 

Log message:
sysv: Recheck message queue limit after malloc

que_create() allocates with M_WAIT and may sleep after sys_msgget()
checks num_ques against msgmni. The kernel lock is released while the
thread sleeps, allowing concurrent creators to pass the same check and
exceed the queue limit.
