In my view this is a blocker for 4.11. With such a bug we cannot say SMP is
available and it was planned to be in 4.11.
Is there a "hold giant lock" level solution ? That is something, even if
performance is poor, that is stable.
I don't know an easy solution for the thread deletion problem, see also
http://www.rtems.org/pipermail/rtems-devel/2013-July/003509.html
A list of other unsupported features can be found here:

The task variable API will never work on SMP (the Ada self rtems_ada_self has
the same problem). For Newlib a similar fixed with the usage of __getreent().
As a result the C++ support is currently broken on SMP.
The non-preempt mode can work on SMP, but I think this would lead to a broken
design.
The bdbuf and the once functions will not work due to that (mutual exclusion
via non-preempt doesn't work on SMP).
