[EZ] OK we need to trace those. But TLS has some bugs too.
We had cases where we could see cond wait events not being picked up.

[EZ] In old Pthread the threads seems like processes and in TLS they do
not. This is not the issue. I suspect that in gen1 we see the cond wait
issue more frequently as the vendor uses cl_timer more often (which uses
cond wait ...)
