Hi Steve,

I have a doubt related to the thread creation in a process
with multiple DLLs loaded in its space.

When a thread is created in this environment,
would kernel notify ALL the DLLs in that process to
allocate TLS[thread local storage for the DLL] for that
thread OR the kernel notifies only the particular DLL for
TLS allocation ?

In case, the kernel notifies all the DLLs in that process,
what is its advantage in doing so, as all the DLLs
may not be used by that thread.

It would be most welcome if you can detail the thread
creation in a process of this environment.

regards
sajid
