[Xenomai] POSIX socket() call switches to secondary mode

Hi
During optimisation I found out that I have a POSIX socket() call for
opening a TCP connection that tends to switch to secondary mode, which
I expected to stay in primary mode. However, then I found a post [1],
which says that it is in fact considered normal behaviour:
"rt_dev_socket may cause a switch to secondary mode, yes, this is
perfectly normal, only sending and receiving data is guaranteed to not
cause a switch to secondary mode."
I also saw that this post was from 2014.... I am wondering now if this
is still considered normal behaviour for the current version of
socket() (POSIX skin of Xenomai 2.4.6 on arm linux 3.0.35)?
Thanks and regards,
Andreas
