[PPL-devel] Problem with PPL

[Enea Zaffanella]

Hello.

The library is not thread safe (yet), so such an error is to be 
expected; we are going to add thread safety in an experimental branch. 
Your multi-threaded application can still use the library, as long as 
only one thread is used to perform all PPL-related computations.

Enea.
