Hi Samir.

The PPL implementation assumes a single thread of execution. Therefore, 
if you want to use it safely in a multi-threaded program, you should 
force all invocations of PPL services to come from a fixed thread. Even 
though there might be special cases where it would be safe to use 
multiple threads, we never really investigated this possibility.
