Hi

Ok, I know BSD ppl may not like it, but anyway I have few questions I
think some of you know the answers.

Sys V ipc (at least the calls related to shared mem and messages queues)
seems to _not_ be implemented as system calls. 

Indeed, ktrace/kdump wont records them as system calls (even if the
manpage for shmat is in section 2 ;=)

I experienced the following: 

- msgrcv() with IPC_NOWAIT return EWOULDBLOCK instead of ENOMSG (Linux
and Sys V)

- a process can have no more than 8 shared mem segments
(how can I change this ?)

Is the above the expected behaviors ?

Can one confirm/infirm  ?

Tia
