FreeBSD 5.2.1 STARLIGHT: morgoth@/usr/src/sys/conf/STARLIGHT amd64     
when send multiple messages of different priority, then when I use 0 in rcv then reciving sorted by priority (this is OK)
but when a set in recv specific positive number (for example 4) and msgtype 4 was send before, I recive nothing and syscall waits forever
I think it isn't good. BTW some IPC functions seem to work different on amd64, my libraries (written by myself) works different on amd64, and THERE ARE NO pointer/interger problems      
 just sendmsg tyype 3 and then rcvmsg of type 3
