i located the issue.
it can be reproduced when cpuing to another machine and
running window -m.
the problem is that OCEXEC doesnt work too tell with
/srv files.
when any program opens a /srv file with OCEXEC flag,
it sets the close-on-exec flag on the shared channel,
resulting in all subsequent opens (regardless of the
flag) to have close-on-exec semantics.
that happens with the $wsys channel.
it is interesting as devsrv itself tries hard to
prevent you from posting a file descriptor with the
close-on-exec flag set. but subsequent opens can
still poison the channel.
the fixes are pushed.
