Here I am not sure to understand. Why do your "cleanup" code per request (the
ttrace::cleanup added) delete the loaded functions ?
They should not be deleted... (I am perhaps missing something, I didn't chek
carefully the cleanup code so far).

It looks like that commenting the ttrace::cleanup code is better for the lock
contention problem. If there is a problem with the cleanup, there will be no
need to split storage into several nsv arrays.
I will try to make tests on our production server with and without the
ttrace::cleanup to see what happens on big load and let you know.
Thanks for your help Zoran !
